Yes, I agree with you both @Krishna and @Ashish.

Yes, agree with @Krishna.

Diesel > duel > Otto.

None of the options are correct. It should be Diesel, dual and otto because if you plot a PV diagram you will find diesel has more area then comes dual and then otto.

Dual cycle, Diesel cycle, Otto cycle it is increasing order.

Otto cycle has high efficiency because of low heat ignition. Is I am right?
