    Answer : Option D

    Explanation :

    The volumetric efficiency represents the efficiency of a compressor cylinder to compress gas. It may be defined as the ratio of the volume of gas actually delivered to the piston displacement, corrected to suction temperature and pressure. The volumetric efficiency of a compressor Decreases with increase in compression ratio
