As the process is cyclic we can first assume that work done is positive. Thus heat extracted would only be in the proces 1 and 2(I am assuming process 1 and 2 to be the sections of the spuare from left to right in the direction of heat flow).So heat will be nCvdT + nCpdT. On calculation you will get your answer 6.5PV i. e option A is correct.
