The correct option is B Adiabatic
Any process is adiabatic is rapid such that there should not be any heat transfer between the system and
it's surroundings. When a tyre bursts suddenly, the expansion takes place instantly. This leads to decrease in temperature inside. As such, the higher
temperature air outside will transfer heat to it. This heat transfer
is not rapid and doesn't take place instantly, unlike the expansion, which is instantaneous. Heat transfer takes place after the bursting, due to which one can
consider that there is almost no energy exchange during the actual
process. Thus process is adiabatic.
