Answer:

The answer is c) on the compression stroke.

Explanation:

The compression stroke is the stroke in an engine in which the air or air/fuel mixture is compressed before ignition. The intake valve closes and the piston starts up on the compression stroke. During the compression stroke, the piston moves up the cylinder, squeezing the fuel-air mix.
