Solution

The correct option is A $W = - q$
For cyclic process, internal energy change $Δ U = 0$ internal energy is a state function. Hence, in a cyclic process, where initial and final states are same,the initial and final internal energies are same.

For cyclic process $W = - q$ . This is because for cyclic process $Δ U = 0$ and $Δ U = W + q$ .
