Option A is correct. As per carnot principle : (1) all the reversible engine working between same temperatures have same Efficiency.
(2) reversible engine have always higher efficiency than irreversible engine working between same temperature range.
(2) reversible engine have always higher efficiency than irreversible engine working between same temperature range.

No engine have more efficiency than carnot cycle and it base on reversible process.

A corollary to Carnot's theorem states that: All reversible engines operating between the same heat reservoirs are equally efficient.

Yes. Option A is write answer. Because all reversible engine are working on carnot cycle, in which the losses are not considered. And that provide the system reversibility. When losses are not considered then for given heat input the engine will give maximum work.

Option A is the right answer because Carnot engine is an ideal and no losses are considered.
Hence, which has more efficiency than irreversible engines.
Hence, which has more efficiency than irreversible engines.

Reversible engines have higher efficiency as Carnot cycle is the reversible cycle and it has maximum efficiency.

Option A is also incorrect as reversible engines operating between different temperature limit will have different efficiency.
Operating between same temperature limit is not stated.
Operating between same temperature limit is not stated.

I think option d is correct.

In irreversible engine heat losses takes place. So the efficiency of Carnot is alway higher than irreversible. So option A is correct.
