option c.... ..........

coz 100% heat given is not changed into workdone .

so efficiency can never be 100%

Tulsirani100: Can you explain please?

Anonymous: check it

Tulsirani100: But in Carnot engine 100% efficiency is possible

Answer:

its c

Explanation:

as no engine can have efficiency greater than that of Carnot's engine.

and its given by

100-T2/T1

as first option is wrong by referring to the above formula.

2nd isnt possible as no engine like this exists

as already stated , Carnot's engine will have max efficiency therefore d is also eliminated.
