This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements.
Statement-I : The magnitude of the work involved in an isothermal expansion is greater than that involved in an adiabatic expansion.
Statement-II : P-V curve (P on y-axis and V on x-axis) decrease more rapidly for reversible adiabatic expansion compared to reversible isothermal expansion starting from same initial state.

Options

A. Statement-I is true, Statement-II is true, Statement-II is a correct explanation of Statement-I
B. Statement-I is true, Statement-II is true, Statement-II is not a correct explanation of Statement-I
C. Statement-I is true, Statement-II is false.
