In the given P–V diagram, a monoatomic gas \(\left( \gamma = \dfrac{5}{3}\right) \) is first compressed adiabatically from state \( A \) to state \( B \). Then it expands isothermally from state \( B \) to state \( C \). [Given: \( \left(\dfrac{1}{3}\right)^{0.6} \simeq 0.5 \), \( \ln 2 \simeq 0.7 \)]

Which of the following statement(s) is(are) correct?
