At equilibrium, the system has reached a state where its entropy is maximized, and any further changes do not result in a net increase or decrease in entropy.
Therefore,
ΔS = 0.
Therefore,
ΔS = 0.

For a spontaneous process of a system, the change in entropy should be always greater than zero and for an equilibrium (more or less reversible) process the entropy must be equal to zero.
So, option C is right.
So, option C is right.

When a system is in equilibrium, the entropy of the system is at a maximum with respect to any any possible changes in the system.
This means that the differential dS = 0, and any finite change in the state of the system would lead to a decrease (or not change) in entropy, so =< 0.
