Detailed explanation-1: -Therefore, the compression ratio is the ratio of Total volume to clearance volume, and the correct option is (C).

Detailed explanation-2: -Clearance volume can also be defined as the difference between the total cylinder volume and the swept volume. The space covered by the clearance volume also forms the combustion chamber. The compression ratio can be defined as the value obtained by dividing the total cylinder volume by the clearance volume.

Detailed explanation-3: -(i) Compression ratio is defined as the ratio between total cylinder volumes to clearance volume. (ii) Cut off ratio is defined as the ratio of volume after the heat addition to volume before the heat addition. (iii) Expansion ratio is the ratio of volume after the expansion to the volume before expansion.

Detailed explanation-4: -Plug your numbers into the formula CR = (Vsw + Vcl) / Vcl. Now that you know the swept volume and clearance volume, simply insert those numbers into the formula and solve it. Add the swept volume and cylinder volume together first. Then, divide the result by the cylinder volume to find the compression ratio.
