    The Congo Basin is a large, tropical rainforest region in central Africa that spans across several countries. The main countries that make up the Congo Basin are:

    1. Democratic Republic of the Congo (DRC) – It holds the largest portion of the Congo Basin and is home to a significant part of the rainforest.
    2. Republic of the Congo – Also known as Congo-Brazzaville, this country has a substantial portion of the Congo rainforest.
    3. Central African Republic – Located to the north of the Congo Basin, it contains part of the rainforest region.
    4. Gabon – Although it has a smaller share, Gabon has a well-preserved part of the Congo Basin rainforest.
    5. Cameroon – The southern part of Cameroon is part of the Congo Basin.
    6. Equatorial Guinea – The mainland region of Equatorial Guinea (Río Muni) is included in the Congo Basin.

    These countries collectively make up the Congo Basin region, which is the second-largest tropical rainforest in the world, after the Amazon. It is known for its rich biodiversity, complex ecosystems, and significant role in regulating the Earth’s climate. So, Cameroon is the correct answer.

    The correct answer is: Honey Bees. Honey bees perform the “waggle dance” to communicate the direction and distance of a food source to other members of their hive. The dance involves a series of movements, including waggling their bodies and making figure-eight patterns, to convey information about the location of nectar, pollen, or water. This sophisticated form of communication is crucial for the foraging efficiency and survival of the colony. Neither butterflies, dragonflies, nor wasps use this method of communication.

    Let’s analyze each statement:

    Statement-I: India, despite having uranium deposits, depends on coal for most of its electricity production. This statement is correct. Although India has some uranium deposits, they are not sufficient to meet the country’s nuclear energy needs. As a result, India imports uranium and heavily relies on coal, which is abundant and cheaper, for most of its electricity production.

    Statement-II: Uranium, enriched to the extent of at least 60%, is required for the production of electricity. This statement is incorrect. For nuclear reactors used in electricity production, uranium is typically enriched to about 3-5% U-235. Enrichment levels of 60% and above are considered high and are used for research reactors or weapons-grade material, not for commercial electricity generation.

    Therefore, the correct answer is: Statement-I is correct but Statement-II is incorrect.

    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.

    2. Nebulae: Nebulae are giant clouds of dust and gas in space, not stars that brighten and dim periodically. The description in the pair is incorrect. Hence, this pair is incorrect.
    3. Pulsars: Pulsars are indeed neutron stars that emit beams of radiation, and they are formed when massive stars run out of fuel and collapse. The description in the pair is accurate. Hence, this pair is correct.

    Therefore, only one of the pairs is correctly matched.
