Answer
Correct option: C.
c
process $BC$ and $AD$ is shown by a dot in $(\rho -V)$ curve.
process $BC$ and $AD$ is shown by a dot in $(\rho -V)$ curve.
It means $BC$ and $AD$ is a isochoric process. So, option $(3)$ is correct

Two Carnot engines $A$ and $B$ are operated in series. Engine $A$ receives heat from a reservoir at $600\,K$ and rejects heat to a reservoir at temperature $T$. Engine $B$ receives; heat rejected by engine $A$ and in turn rejects it to a reservoir at $100\,K$. If the efficiencies of the two engines $A$ and $B$ are represented by ${\eta _A}$ and ${\eta _B}$ respectively, then what is the value of $\frac{{{\eta _A}}}{{{\eta _B}}}$
→If one mole of an ideal gas at $\left( P _{1}, V _{1}\right)$ is allowed to expand reversibly and isothermally ($A$ to $B$ ) its pressure is reduced to one-half of the original pressure (see $figure$). This is followed by a constant volume cooling till its pressure is reduced to one-fourth of the initial value $( B \rightarrow C ) .$ Then it is restored to its initial state by a reversible adiabatic compression ($C$ to $A$). The net workdone by the gas is equal to ...... .
