This is not a correct representation, for T-s of an Otto process 1-2 isentropic compression starts from low temp to high.

But the maximum temperature in otto cycle at point 3 in T-S diagram.
I think there is something wrong in all figures.

In otto cycle is a constant volume cycle At the given temp. And entropy remain constant (so answer C is correct).

It is a wrong diagram.
Process 1 to 2 is compression process so temp will always increase rather than decrease.

In otto cycle, there is two isentropic processes, two constant volume processes so, the answer is C.

Otto cycle consist of two constant volume & other two is isentropic.
So C is right answer.
So C is right answer.

Otto cycle works on petrol engine so this is a constant volume process so option C is correct.

There are 2 isochoric and 2 isentropic processes. It works on petrol engine also.

Otto cycle consists of two isentropic process and two constant volume process.

Yes otto cycle consists of two constant volume and two isentropic processes.
