We know that in first law of thermodynamics the heat supplied is used to cahnge the internal enegy and is used to do the work.So in the first case since the volume is kept constant the work done is taken as 0 whereas in the second case since the work done is actually positive the change in internal energy is lee than that in first case.So the answer is option .
