Answer

The measurement that corresponds to constant pressure must be measurement B, since some of the energy released must do work on the surroundings.

Therefore, the measurement for constant pressure must be smaller than the measurement for constant volume. This means that the measurement that corresponds to measurement A, the larger of the two, must be for constant volume because all of the energy transferred to the surroundings is in the form of heat.
