Change in entropy ds = dq/T.
ds is directly proportional to dq.
ds is directly proportional to dq.

Heat addition increase in entropy and Heat rejection decrease in entropy.

In a reversible process entropy remains constant. Then how can it be the answer?

Its answer should be Enthalpy.
Because entropy change is zero in case of isotropic process, where heat interactions are involved unlike adiabatic process (no heat interactions).
As, we all know that every reversible adiabatic is isotropic but every isotropic is not reversible adiabatic. So even if the heat interaction is there, there might be no entropy change.

Why not enthalpy comes as a answer? Please tell me the differ between enthalpy and entropy.

Since entropy change can never be negative though as per question it is enthalpy.
