Irreversible process is the correct answer.
If these processes are non-flow processes then we can call them reversible process.

@All.
The otto and diesel cycles are irreversible so the constant pressure and constant volumes are irreversible processes.
The otto and diesel cycles are irreversible so the constant pressure and constant volumes are irreversible processes.

The constant pressure, constant volume and constant pvn processes are regarded as REVERSIBLE process. So, the answer is B.

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.

Throttling process and expansion process are irreversible process. But CV and cp and CT are reversible process.

No, the Constant pressure process practically not possible. Only throttling process is irreversible process.

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

Is that these processes can not back their initial stage then which process get back their initial stage.

The answer is wrong. All the process like constant pressure, constant volume are a reversible process.
