(1) If both Assertion (A) and Reason (R) are True and the Reason (R) is a correct explanation of the Assertion (A).
(2) If both Assertion (A) and Reason (R) are True but Reason (R) is not a correct explanation of the Assertion (A).
(3) If Assertion (A) is True but the Reason (R) is False.
(4) If Assertion (A) is False but Reason (R) is True.
Assertion (A): Enthalpy and entropy of any elementary substance in the standard states are taken as zero.
Reason (R): At absolute zero, the entropy of the perfectly crystalline substance is equal to zero.
