    Question

    What was the primary effect of Deccan Volcanism on the

    fauna according to recent research?
    A It increased the diversity of fauna species. Correct Answer Incorrect Answer
    B It had no significant impact on fauna. Correct Answer Incorrect Answer
    C It contributed to the mass extinctions of dinosaurs and other fauna. Correct Answer Incorrect Answer
    D It promoted the evolution of new faunal species. Correct Answer Incorrect Answer
    E It reduced the habitat areas for fauna but did not cause extinctions. Correct Answer Incorrect Answer

    Solution

    The study highlighted that Deccan Volcanism played a significant role in causing mass extinctions of various fauna, including dinosaurs. This catastrophic event aligns with the broader Cretaceous-Paleogene (K-Pg) mass extinction event, which saw a dramatic reduction in biodiversity globally. The volcanic activity likely created severe environmental conditions, such as toxic gases and temperature changes, that were inhospitable for many faunal species, leading to their decline and eventual extinction.
