Correct answer: C If assertion is true but reason is false.

NCERT states “The Western Ghats have a greater amphibian species diversity than the Eastern Ghats.” The Assertion is true - there is indeed a difference in amphibian diversity between these regions. However, the Reason is false - it reverses the relationship. NCERT clearly states Western Ghats have greater diversity, not Eastern Ghats.
