(A): Ethene is more reactive than ethane
(R):

\mathrm{C}=\mathrm{C}

bond energy in ethene is more than that in ethane

View answer and explanation

Correct option: B

Both A and R are correct, R is not the correct explanation of A

Option B (Both A and R are correct, R is not the correct explanation of A) is correct because ethene is indeed more reactive than ethane, but the reason is due to the presence of the pi bond, not the overall bond energy.
