### Isomorphism

1. The problem statement, all variables and given/known data

2. Relevant equations and the attempt at a solution:
AC is adiabatic and AB is isothermal.

Heat absorbed during process AC = 0 (adiabatic).
Heat absorbed during process CB = $$C_p \triangle T=-\frac{\gamma}{\gamma -1} (P_2V_3 - P_2V_2)$$
Heat absorbed during process BA = $$RT\ln \frac{V_3}{V_1}$$

Summing it up, does not give any of the options. What went wrong?
