An isobaric process is a thermodynamic process in which the pressure remains constant.

A Thermodynamic process in which volume remains constant is known as the Isochoric Process.

When a thermodynamic system undergoes a thermodynamic process in such a way that its temperature remains constant, then that process is called an Isothermal process.

A process in which no heat can enter or leave the system is called an adiabatic process.

”In an adiabatic process, there is no transfer of heat across the boundary of the system, so Q=0

i.e In an adiabatic process the system is insulated from the surroundings

and in adiabatic process  {\rm{PV}}^\gamma = constant

So option A is correct
