Solution

The correct option is A Isothermal process
In thermodynamic processes,
work done = Area covered under $P V$ curve

As the curve of isothermal lies above the adiabatic curve it is clear that $(A r e a)_{i s o} > (A r e a)_{a d i} s o, W_{i s o} > W_{a d i}$
There is a temperature loss in adiabatic process.
