Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).\n Assertion (A): For an ideal gas undergoing a process, the heat absorbed at constant pressure is greater than the heat absorbed at constant volume for the same temperature rise.\n Reason (R): At constant pressure, a part of the energy supplied is used in doing expansion work against external pressure. \nIn the light of the above statements, choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. (A) is true but (R) is false.
4. (A) is false but (R) is true.
