The answer should be option A.
Carnot cycye consists of reversible adiabatic processes.
For reversible process we know;
dS=dQ/T.
For the adiabatic process, we know dQ =0.
So dS=0
So S2-S1=0
So S2=S1.
Means Caront cycle should be called a constant entropy process.

The Carnot cycle is a thermodynamic cycle that gives the best efficiency possible. Given an amount of energy in form of heat, the Carnot cycle transforms heat put in to produce useful work by a series of reversible adiabatic (isentropic) and isothermal processes.
The efficiency of a Carnot engine is one minus the ratio of the temperature of the hot thermal reservoir to the temperature of the cold reservoir.
