The answer is A. Hope this helps!!!

Answer:

A.

Explanation:

Compression ratio of an engine is defined as the ratio of the volume of gas in cylinder when the position is at TDC ( top dead center ) means top of its stroke to the volume of the gas when piston is at the bottom which is BDC or bottom dead center.

So if an engine has a compression ratio of 7 :  1 then it means the air and fuel mixture in the cylinder is squeezed into a space that is seven times smaller during the compression stage.
