Topic: JEE PYQ

Answer: D. Full step-by-step solution below.

  1. AStatement-1 is True,Statement-2 is True; Statement-2 is a correct explanation forStatement-1.
  2. BStatement-1 is True, Statement-2 is True; Statement-2 is NOT a correct explanation for Statement-1.
  3. CStatement-1 is True, Statement-2 is False.
  4. DStatement-1 is False, Statement-2 is True.

Correct answer: D
