A gas is expanded from volume \( V_{0} \) to \( 2 V_{0} \) under three different processes. Process 1 is isobaric, Process 2 is isothermal
\( \mathrm{P} \) and process 3 is adiabatic. Let \( \Delta U_{1}, \Delta U_{2} \) and \( \Delta U_{3} \) be the change

W in internal energy of the gas in these three processes. Then :
(A) \( \Delta U_{1}\Delta U_{2}\Delta U_{3} \)
(B) \( \Delta U_{1}\Delta U_{2}\Delta U_{3} \)
(C) \( \Delta U_{2}\Delta U_{1}\Delta U_{3} \)
(D) \( \Delta U_{2}\Delta U_{3}\Delta U_{1} \)
