For specified limits for the maximum and minimum temperature

Solution

Solution :

So if we consider all the cycles and Carnot has the highest efficiency and also stirling and ericson cycles have been designed to operaate at maximum efficiency.

Hence the answer should be otto cycle or diesel cycle since any options are not given.

Again if we compare the otto and diesel cycle the Diesel cycle has lower efficinecy when compared to otto hence the asnwer would be Diesel cycle.
