The correct answer is: $\mathrm{A}$ and $\mathrm{R}$ and true and $\mathrm{R}$ is correct explanation of A.
When an ideal gas is compressed adiabatically, its temperature and the average kinetic energy of the gas molecule increases because of collision of molecules with wall. Hence, Both A and R are true and R is the correct explanation of A.
