Best answer
Correct option is (a) Wrev > Wirr

Explanation: A process is irreversible due to dissipative forces or free expansion or explosive chemical reactions and so on. This causes it to lose the amount of useful work that can be done in an irreversible process. This is not the case for a reversible process. Hence, Wrev > Wirr.
