The thermal efficiency of Brayton cycle

Question

Direction: Each of the next consists of two statements, one labeled as the ‘Assertion (A)’ and the other as carefully and select the answers to these item using the codes given below:

Codes:

1. Both A and R are individually true and R is the correct explanation of A
2. Bothe A and R are individually 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                                              

Assertion (A): The thermal efficiency of Brayton cycle would not necessarily increases the reheat

Reason (R): Constant pressure lines on the T-s diagram slightly diverge with increases in entropy.
