For Same compression ration:.
Efficiency of Otto cycle is greater than that of Diesel cycle and efficiency of Dual cycle is in-between Otto and Diesel cycles.
Efficiency of Otto cycle is greater than that of Diesel cycle and efficiency of Dual cycle is in-between Otto and Diesel cycles.

For the same compression ratio the efficiency of diesel cycle is more than Otto Cycle. And the dual combustion cycle is in between the Otto and diesel cycle. And I think option B is correct.

Yes I m agree with your answer.
Efficiency of diesel cycle is more than otto cycle. And the dual combustion cycle is in between of them.
B option is right I think.
Efficiency of diesel cycle is more than otto cycle. And the dual combustion cycle is in between of them.
B option is right I think.

For same compression ratio.
Otto cycle > duel dycle > diesel cycle.
Otto cycle > duel dycle > diesel cycle.

For the same compression ratio=> n)otto > n)dual> n)diesel cycle {where n represent efficiency}.
So, option A is correct.
So, option A is correct.

Otto cycle more efficient then other cycles.

Carnot cycle is more efficient than other cycle.

For the same compression ratio, the area under PV diagram is maximum for otto cycle. So the efficiency is the maximum for otto cycle followed by dual and diesel cycle.

But which efficiency mechanical or thermal?

For same compression ratio, In case of diesel cycle heat rejection will be more compared to Otto cycle. (area under T-S dia, slope for constant volume is more than that of constant pressure) And since heat is rejected under conatant volume and added under constant pressure in case of diesel cycle, thermal efficiency of diesel cycle is less than that of Otto.
