Exhaust is an assumed constant pressure process like suction. So, the answer should be option A.

During exhaust, Pressure must be greater than the atmospheric pressure unless leakage of air will take place and hence it will decrease the efficiency.

It is equal, the valves exhaust stroke is opened and piston pushes gases to ATM at ATM pressure only.

It should be lower because while suction stroke volume increase suddenly.
