Question

Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R. Assertion A : H2Te is more acidic than H2S. Reason R: Bond dissociation enthalpy of H2Te is lower than H2S. In the light of the above statements. Choose the most appropriate from the options given below.

(A) Both A and R are true but R is NOT the correct explanation of A.
(B) Both A and R are true and R is the correct explanation of A.
(C) A is false but R is true.
(D) A is true but R is false.
