    Answer : Option D

    Explanation :

    If p₁ is the pressure of air entering the L.P, cylinder and p₃ is the pressure of air leaving the H.P. cylinder, then the ratio of cylinder diameters for a single acting, two stage reciprocating compressor with complete intercooling is given by D₁/D₂ = (p₃/p₁)1/4
