Correct answer
Birreversible adiabatic

Step-by-step explanation

A thermodynamic process that happens without transmitting heat or mass between the thermodynamic system and its surroundings is known as an adiabatic process.

An irreversible process is one in which the system and its surroundings are unable to revert to their original states.

Bursting of a balloon is an irreversible adiabatic process, because energy can not be restored in this process.
