A

B

C

D

## Text solution Verified

Using the first law of thermodynamics,

Since the gas is heated at constant pressure we can say that,

Heat supplied to the gas at constant pressure

Also, ,

Heat absorbed by the gas to increase its temperature is

Hence, fraction of heat used to raise the temperature is given by
