    The correct answer is All three.

    Here’s how an accelerometer is involved in each action:

    1. Detection of Car Crash/Collision

    • An accelerometer detects rapid deceleration or impact forces, which triggers the deployment of airbags almost instantaneously.
    • Function of accelerometer: Required.

    2. Detection of Free Fall of a Laptop

    • Accelerometers sense sudden free-fall motion (near-zero acceleration in free fall) and can signal the hard drive to turn off immediately to prevent damage.
    • Function of accelerometer: Required.

    3. Detection of Tilt of a Smartphone

    • Accelerometers measure the tilt or orientation of the device relative to gravity, allowing the display to rotate between portrait and landscape modes.
    • Function of accelerometer: Required.

    An accelerometer is required in all three actions, as it plays a crucial role in detecting motion, orientation, or force changes in each scenario. Thus, the correct answer is All three.

    Let’s analyze the statements:

    Statement-I: Marsupials are not naturally found in India. This statement is correct. Marsupials, such as kangaroos and koalas, are primarily found in Australia and nearby islands. They are not native to India.

    Statement-II: Marsupials can thrive only in montane grasslands with no predators. This statement is incorrect. Marsupials inhabit a wide variety of environments, including forests, grasslands, and deserts. They are not limited to montane grasslands and can coexist with predators, as evidenced by their presence in diverse habitats in Australia, where they have adapted to various ecological niches.

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

    Indonesia has rapidly ascended to the position of the world’s second-largest cobalt producer, leading to a substantial decline in the price of this essential battery metal and intensifying Western concerns over China’s stronghold in the electric vehicle supply chain. Last year, the Southeast Asian nation produced 9,500 tonnes of cobalt, representing 5 percent of the global supply, a significant leap from its negligible production levels before 2021. Nevertheless, Indonesia still trails significantly behind the Democratic Republic of Congo, the top global supplier, which commands a dominant 73 percent share of the market. So, the correct answer is: The Democratic Republic of the Congo

    Correct Answer: Infrared waves are largely absorbed by water vapor that is concentrated in the lower atmosphere.

    Explanation:

    1. “The total amount of insolation received at the equator is roughly about 10 times that received at the poles.”
      Incorrect.
      While there is a significant difference in insolation between the equator and the poles due to the angle of incidence of solar radiation, it is not as extreme as 10 times. The actual difference is much smaller, generally ranging from 2 to 3 times.
    2. “Infrared rays constitute roughly two-thirds of insolation.”
      Incorrect.
      Infrared rays are part of the electromagnetic spectrum, but they only constitute a small portion of the incoming solar radiation (insolation). The majority of insolation consists of visible light and ultraviolet radiation.
    3. “Infrared waves are largely absorbed by water vapor that is concentrated in the lower atmosphere.”
      Correct.
      Infrared waves, which are long-wavelength radiation, are absorbed by greenhouse gases such as water vapor, carbon dioxide, and methane. Water vapor, concentrated in the lower atmosphere (troposphere), plays a major role in absorbing and trapping infrared radiation, contributing to the greenhouse effect.
    4. “Infrared waves are a part of the visible spectrum of electromagnetic waves of solar radiation.”
      Incorrect.
      Infrared waves are not part of the visible spectrum. The visible spectrum includes wavelengths between 400-700 nanometers, whereas infrared waves are longer than this range and are not visible to the human eye.

    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 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.
