An ideal gas goes through a reversible cycle a→b→c→d has the V - T diagram shown below. Process $\displaystyle \mathrm{d} \rightarrow \mathrm{a}$ and $\displaystyle \mathrm{b} \rightarrow \mathrm{c}$ are adiabatic.The corresponding P - V diagram for the process is (all figures are schematic and not drawn to scale) :
