These processes are either reversible or irreversible.
Reversible processes are one which returns to its original state without leaving any effect on the surrounding.
As per Khurmi, the correct answer is TRUE.

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.

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