Answer 2

I believe there is an equation for the work done by a gas and name of the step A. compression would fit into quite nicely. The compression step involves work being done on a system of gases as the piston compresses the air/ air-fuel mixture inside of the piston. I think the equation was like W = PDeltaV.

Answer 3

so your answer would be A.
