    Correct Answer: Statement-I is incorrect but Statement-II is correct

    Explanation:

    1. Statement-I: “The soil in tropical rain forests is rich in nutrients.”
      Incorrect.
      The soil in tropical rainforests is typically poor in nutrients. This is because heavy rainfall causes leaching, washing away nutrients from the topsoil. Most of the nutrients in tropical rainforests are found in the biomass (plants and trees) rather than in the soil.
    2. Statement-II: “The high temperature and moisture of tropical rain forests cause dead organic matter in the soil to decompose quickly.”
      Correct.
      Tropical rainforests experience warm and humid conditions, which accelerate the decomposition of organic matter. This rapid decomposition ensures that nutrients are quickly absorbed by plants, leaving little in the soil.

    Conclusion:

    The soil in tropical rainforests is nutrient-poor, despite the rapid decomposition of organic matter due to the high temperature and moisture.
    Thus, Statement-I is incorrect, but Statement-II is correct.

    India possesses substantial reserves of heavy minerals predominantly located along its coastal regions and in inland placer deposits. These heavy mineral sands include a collection of seven key minerals: ilmenite, leucoxene (also known as brown ilmenite), rutile, zircon, sillimanite, garnet, and monazite. Among these, ilmenite (FeO.TiO₂) and rutile (TiO₂) are the principal sources of titanium. Titanium dioxide is found in various polymorphic forms, namely rutile, anatase (octahedrite), and brookite. The correct answer is: Titanium.

    The country that has its own satellite navigation system is Japan. Japan’s satellite navigation system is called QZSS (Quasi-Zenith Satellite System), which provides satellite-based positioning and timing information, mainly in the Asia-Pacific region.

    • Australia, Canada, and Israel do not have their own independent satellite navigation systems like Japan.

    So, the correct answer is: Japan.

    Let’s evaluate the above statements:

    1. Amarkantak Hill:
      • Recognized as a significant natural heritage site.
      • Serves as the junction of the Vindhya and Satpura Ranges.
      • Therefore, statement 1 is INCORRECT.
    2. Biligirirangan Hills:
      • Located in the southeastern region of Karnataka.
      • The Satpura Range, in contrast, begins in eastern Gujarat and extends eastward, bordering Maharashtra and Madhya Pradesh, ultimately reaching Chhattisgarh.
      • Hence, statement 2 is INCORRECT.
    3. Seshachalam Hills:
      • Part of the Eastern Ghats in southern Andhra Pradesh.
      • The Western Ghats, however, span across several states including Kerala, Tamil Nadu, Karnataka, Goa, Maharashtra, and Gujarat.
      • Thus, statement 3 is INCORRECT.

    Therefore, the correct answer is None.

    The correct answer is: Bahadur Shah.

    Explanation:

    Bahadur Shah, the Sultan of Gujarat, is the ruler who surrendered Diu to the Portuguese in the early 16th century.

    • In 1535, Bahadur Shah faced a defeat against the Portuguese and, under pressure, surrendered Diu to them in exchange for peace. This event significantly strengthened Portuguese influence in the region.

    Why the Other Options Are Incorrect:

    1. Ahmad Shah: He was the founder of the Gujarat Sultanate and ruled from 1411 to 1442. He was not involved in the surrender of Diu to the Portuguese.
    2. Mahmud Begarha: He ruled from 1458 to 1511 and was a strong ruler of Gujarat. He resisted the Portuguese, especially when they attempted to establish their dominance in the region, and did not surrender Diu.
    3. Muhammad Shah: He ruled in the 16th century but was not involved in the surrender of Diu to the Portuguese.

    Conclusion:

    It was Bahadur Shah who surrendered Diu to the Portuguese after facing defeat.

    Here’s an explanation for each statement:

    1. Some microorganisms can grow in environments with temperatures above the boiling point of water: This is correct. Certain microorganisms, known as thermophiles or hyperthermophiles, can thrive in extremely hot environments, such as hydrothermal vents, where temperatures exceed 100°C (the boiling point of water at sea level).
    2. Some microorganisms can grow in environments with temperatures below the freezing point of water: This is correct. Psychrophiles are microorganisms that can grow in extremely cold environments, including those with temperatures below 0°C, such as in polar regions or glaciers.
    3. Some microorganisms can grow in a highly acidic environment with a pH below 3: This is correct. Acidophiles are microorganisms that can thrive in highly acidic conditions, including environments with pH levels as low as 1, such as in acid mine drainage or acidic hot springs.

    Thus, all three statements are correct. The correct answer is All three.

The Rann of Kutch in Gujarat, India, is a vast salt marshland that was formed due to the geological processes involving tectonic activity and fluctuations in sea level over time. These repeated sea level changes have contributed to the unique landscape of salt flats and marshes in the region.

    Let’s analyze the statements:

    Statement I:
    The Supreme Court of India has held in some judgments that reservation policies made under Article 16(4) would be limited by Article 335 to maintain the efficiency of administration.
    This is correct. The Supreme Court, in various rulings (such as the Indra Sawhney case), has emphasized that while Article 16(4) provides for reservations in public employment, it must be balanced with Article 335, which states that the claims of Scheduled Castes and Scheduled Tribes must be consistent with maintaining the efficiency of administration.

    Statement II:
    Article 335 defines the term “efficiency of administration.”
    This is incorrect. Article 335 does not define “efficiency of administration.” It only mentions that the claims of Scheduled Castes and Scheduled Tribes should be taken into consideration, consistent with the maintenance of efficiency of administration. However, it does not provide a definition of “efficiency.”

    Correct answer:
    Statement-I is correct but Statement-II is incorrect
