Solution

The correct option is A Both assertion (A) and reason (R) are correct and R gives the correct explanation
The ideal gas equation $P V = η R T$ tells us that the pressure and volume are directly proportional to the temperature. The coefficients of expansion for pressure is $γ_{p}$ and that of volume is $α_{v}$ .
