Answer : Option A
Explanation :
An adiabatic process is one that occurs without transfer of heat or matter between a thermodynamic system and its surroundings. In an adiabatic process, energy is transferred only as work.
Rarefaction is the reduction of an item’s density, the opposite of compression.
