Assertion (A): A reaction which is spontaneous and accompained by decreases of randomness must be exothermic.
Reason (R ) : All exothermic reactions are accompained by decrease of randomness.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reason is false

D

If both assertion and reason are false.
