Answer:

Explanation:

Option c is incorrect i.e. Entropy of an isolated  system must be conserved

The entropy of an isolated system always increases. This can be explained by considering the system is isolated so there is no exchange of mass i.e. entropy cannot decrease so it must either increase or remains constant. But due to the presence of spontaneity in the system, there is always an increase in mass unless the system is undergoing a reversible process in which each state change is in equilibrium condition.
