It should be false because for air standard cycles all processes except Throttling process are reversible.

Yes, the correct answer is false.

Answer is false because it depends on the way the process is taking i.e. reversibly or irreversibly. So it can be reversible or irreversible.

Please tell me the correct answer for this question.

Only throttling process is irreversible, so, the answer is false.

Only throttling and free expansion process are the irreversible process. Except these all are the reversible process so the answer is false.

Practically they are irreversible but are considered Internally reversible like in reciprocaing engine. And that's why equation is defined for them and also these processes are shown by solid lines in diagrams.

Const pressure Const volume. Polytropic process are non-flow reversible process. So false is the correct answer.

Constant pressure, Constant volume, and polytropic process (PV^n) is REVERSIBLE.
The correct answer is FALSE.
The correct answer is FALSE.
