Answer:
I guess the law is P×V = RT (constant for the given temperature.)
Let inital state of pressure and volume is P1 and V1. Let the final state of pressure and volume is P2 and V2.
then workdone to get the final state from initial state is P2×V2 - P1×V1 = R(T2-T1)
Hence except (A) all other options are not correct
