Choice D.

Work Step by Step

Isothermal is not the same as adiabatic. Heat can be absorbed or released, so statement (i) is false. For an ideal gas, the temperature is proportional to the gas’s internal energy, and the average translational KE is directly proportional to the absolute temperature. Since the temperature stays constant here, statements (ii) and (iii) are both true.
