In reversible process initial states to final states and can be back to initial. And these process do not came in initial state.
Then these process is irreversible process.
Then these process is irreversible process.

In short all the above-mentioned processes are irreversible in reality. But if the equation is defined as a process then it is considered reversible approximately.

All the above-mentioned processes is regarded irreversible process.
Because all process is reversible when processes are completed with the help of regenerator.

I read in Khurmi Book, he mentioned that all process is reversible other then polytropic, polytropic is an irreversible process.
As per Khurmi Answer is FALSE.
As per Khurmi Answer is FALSE.

Constant volume constant pressure constant temperature isothermal process and pvn is a reversible process.
And throttling is an irreversible process.
And throttling is an irreversible process.

Irreversibility is related to entropy, we can see the above-mentioned processes follow a curve in a T-s diagram and hence they are irreversible.

They didn't mention the process undergoing whether with or without regeneration. So how it will be? Please anyone explain the answer clearly.

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.

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

When initial state is identical to final state it is called cycle. Above this process are hypothecal but reversible. So, answer is B.
