A is the correct answer because compressible liquid above critical points became supercritical fluid.

If the substance is already at the liquid form at a critical pressure, that means that substance is either at critical temperature or below that. In this particular case, on further increase in pressure, we will always have liquid. So, option A is correct.

Critical temperature and critical pressure correspond to the critical point in TTT diagram. Above critical point the gas will remain gas and a liquid will remain liquid no matter the increase in temperature or pressure and this state is known as a supercritical fluid.

I thin both option A & D are correct.
