Here they are asking for liquid.

And for liquid critical values are those above which liquid directly flash off into gaseous phase.

i.e Vapour.

So, I think the answer must be C.

Critical pressure means the pressure at critical temperature. Critical temperature is temperature above which the gas cannot be liquefied even by increasing the pressure.

Critical pressure means pressure at which liquid convert into gas.

The critical temperature of a substance is the temperature at and above which vapor of the substance cannot be liquefied, no matter how much pressure is applied.

The critical pressure of a substance is the pressure required to liquefy a gas at its critical temperature.

A is the correct answer since it tells critical pressure of liquid not gas.

Dibakar said:   7 years ago
Yes, you are right @Uzumaki.
