@Aman.
Thanks for such a type of explanation and clearing our doubt.

As For otto cycle, Air is taken as standard fuel, so gamma becomes constant. That is why efficiency depends on compression ratio only.

For different diatomic molecules, specific heat may vary but gamma remains constant. Which means they have same efficiency even if their specific heats are different.

The efficiency of Otto cycle depends only on compression ratio.
Because the derivation is carried out by taking an assumption that specific heats (Cp and Cv) are constant.
Hence, the answer should be B.

Answer is correct, it depends on comprssion ratio.

Gamma is Cp/Cv.
It Means the ratio of specific heat at constant pressure to specific heat at constant volume.

What is gamma here?

As per the formula of efficiency for the Otto cycle answer should be A "yes".

Actually specific heats depends on gamma and R. Gamma depends on molecular structure. R depends on molecular weight. So answer B can be correct.
