Answer #1

a) the change in system entropy depends on the initial and final states of the system.

TRUE .

Entropy is a state function thus deltaS depend on the final and initial states of the ststem , but not on path followed.

b) False  

anyirreversible process results in overall increase in total entropy NOT system entropy.

c) TRUE

In spontaneous process, the total entropy of universe increases.

d) TRUE

more microstates of system , more randomness, more entropy.
