💡 Solution & Explanation

On a $P-V$ diagram, the curve for an adiabatic reversible expansion is steeper than that for an isothermal reversible expansion. Starting from the same state and expanding to the same final volume, the adiabatic curve drops to a lower pressure. The area under the curve (magnitude of work) is therefore smaller. Statement II correctly explains Statement I.
