If p₁, is the pressure of air entering the L.P. cylinder and p₂ is the pressure of air leaving the L.P. cylinder (or intercooler pressure), then the ratio of cylinder diameters for a single acting, two stage reciprocating air compressor with complete intercooling is given by (where D₁ = Dia. of L.P. cylinder, and D₂ = Dia. of H.P. cylinder)

A. D₁/D₂ = p₁ p₂

B. D₁/D₂ = p₁/p₂

C. D₁/D₂ = p₂/p₁

D. None of these
