Verified answer
In a cyclic process, the system returns to its initial state and but not a reversible. And the change in internal energy must be zero.
ΔU=0
From 1st law of thermodynamics,
ΔQ=ΔU+ΔW
ΔQ=0+ΔW
ΔQ=ΔW
The total heat absorbed by the system is equal to the work done by the system.
The correct option is D.
