Solution
The correct option is A critical temperature Boiling point of a liquid is the temperature at which vapour pressure of the liquid is equal to external pressure on the liquid.
Freezing point of a liquid is the temperature at which the liquid and solid phases of the liquid are at equilibrium.
Critical temperature is the temperature at which boundary between vapour and liquid phases of liquid disappears when the liquid is heated in a closed vessel.
Therefore critical temperature is the correct answer.
