Hint:
We know that the chemical equilibrium is that state in which the reactants and products exist in deliberations which generally don’t have a further affinity to change with respect to time.

Complete step by step solution
As we know that, the chemical equilibrium is that state in which the curve of reactant and product does not change with respect to time, and it happens in a closed system. The vapour pressure is that pressure which generally can be exerted by vapour or gas by the thermodynamic equilibrium at a specific temperature. The general meaning of vapour is the gaseous phase. In the vapour pressure process, the temperature of the closed system gradually increases.

Thus, the pressure at which liquid and the vapour can coexist at equilibrium is called the saturated vapour pressure. The saturated vapour pressure shows the pressure which reaches at the saturation point during the chemical equilibrium reaction.

Hence, the correct choice for the given question is D that is saturated vapour pressure.

Note:

The saturated vapour pressure is that pressure which gets saturated or attains the saturation point in any closed system with respect to a specific temperature in kelvin.
