# S1: Reversible process and cyclic process have same meaning.  S2: $\Delta H_{cycle}$ and $\Delta E_{cycle}$ is zero.

$\begin {array} {1 1} (A)\;\text{If both S1 & S2 are correct and S2 is correct explanation of S1.} \\ (B)\;\text{If both S2 & S1 are correct but S2 is not correct explanation of S1.} \\ (C)\;\text{If S1 is correct but S2 is wrong.} \\ (D)\; \text{If S1 is wrong but S2 is correct.} \end {array}$

Every cyclic process is a reversible process, but every reversible process is not a cyclic process.
Ans : (D)
