Second law of thermodynamics can be stated as :
“The total entropy of an isolated system that undergoes a change can never decrease.” Furthermore if  the process is irreversible, then the total entropy of an isolated system always increases. In a reversible process, the total entropy of an isolated system remains constant.
The correct answer is: remains constant

Reversible Process and Entropy

Reversible processes are idealized processes that can be reversed without causing any net change in either the system or its surroundings. In a reversible process, the entropy of the system remains constant.

Explanation:
- In a reversible process, the system undergoes changes in such a way that it can be returned to its original state without leaving any trace on the surroundings.
- Since entropy is a measure of the disorder or randomness of a system, in a reversible process, the system's disorder remains constant.
- This is because the system goes through infinitesimally small changes, ensuring that the system's entropy does not increase or decrease during the process.
- As a result, the entropy of a system in a reversible process is constant throughout the process, distinguishing it from irreversible processes where entropy either increases or remains constant.

Therefore, in a reversible process, the entropy of the system remains constant as the system undergoes changes in a way that allows it to be returned to its original state without any net change in entropy.
