An ideal gas goes from State A to state B via three different process as indicate in the `P-V` diagram.

If `Q_(2), Q_(3)` indicates the heat absorbed by the gas along the three processes and `DeltaU_(1), DeltaU_(2), DeltaU_(3)` indicates the change in internal energy along the three processes respectively, then

Options

A. `Q_(1)gtQ_(2)gtQ_(3)and DeltaU_(1)=DeltaU_(2)=DeltaU_(3)`
B. `Q_(3)gtQ_(2)gtQ_(1)and DeltaU_(1)=DeltaU_(2)=DeltaU_(3)`
C. `Q_(1)=Q_(2)=Q_(3)and DeltaU_(1)gtDeltaU_(2)gtDeltaU_(3)`
D. `Q_(3)gtQ_(2)gtQ_(1)and DeltaU_(1)gtDeltaU_(2)gtDeltaU_(3)`
