No, the process is reversible by default but can be made reversible using elements like regenerator.

It is a polytropic process, p is pressure, we is volume and n is polytropic index.

Answer is wrong. It is also reversible process. So false is correct answer.

How we can say that all of above is irreversible process? please tell me.

Incorrect is the answer because all these processes are reversible.
