If \( P \) and \( Q \) are two statement, then which of the follwing compound statement is a tautology?
(PV)
(a) \( (P \Rightarrow Q) \wedge \sim Q) \Rightarrow Q \)
(b) \( ((P \Rightarrow Q) \wedge \sim Q) \Rightarrow \sim P \)
(c) \( ((P \Rightarrow Q) \wedge \sim Q) \Rightarrow P \)
(d) \( ((P \Rightarrow Q) \wedge \sim Q) \Rightarrow(P \wedge Q) \)
