I think you are correct @Joe.

For option A to be correct, they might have meant a process which is isothermal and adiabatic.

In that case, that process will be reversible since no heat exchange and no internal temperature changes (no dissipative effects).

There will be both reversible and irreversible adabatic process.

Reversible process: isothermal, adiabatic, Carnot, Starling, Ericson.

Irreversible: entropy increase, Cp, Cv, PVn.

If you have an adiabatic reversible path that takes you from state 1 to state 2, any irreversible path from state 1 to state 2 will require removal of heat, so it won't be adiabatic. This is a consequence of the 2nd law of thermodynamics, captured by the Clausius Inequality.

Option C is the correct one.

Isothermal and adiabatic are common names.

A reversible isothermal process is called Hyperbolic process.

A reversible adiabatic process is called iso-entropic process.

Option C may be correct.

If it is adiabatic process means, then there will be no heat loss. So no loss means it must be reversible process.

Adiabatic could be irreversible also.
