Adiabatic Expansion:
Adiabatic expansion is a thermodynamic process in which a gas expands without transferring heat or matter between the system and surroundings. In this process, the internal energy of the gas decreases, and the temperature and pressure of the gas decrease.
Pressure-Volume Product:
The pressure-volume product is the product of pressure and volume of a gas. In an adiabatic expansion, the pressure-volume product changes due to the expansion of the gas.
Effect of Adiabatic Expansion on Pressure-Volume Product:
During the adiabatic expansion, the gas expands, and the volume of the gas increases. As a result, the pressure of the gas decreases. Therefore, the product of pressure and volume also decreases.
Hence, the correct answer is option 'A,' i.e., decreases.
Conclusion:
In an adiabatic expansion, the product of pressure and volume decreases due to the decrease in pressure of the gas caused by the expansion. This process is important in understanding the behavior of gases and is used in various industrial and scientific applications.

As we know in adiabatic process
∆U = w
So the work done in expansion would be used from ∆U which is equal to (fnRdT)/2. Which will result in decrease in T(temperature).
In equation PV=nRT as T will decrease n and R being constant PV will also decrease.
