Solution

The correct option is C The vapor pressure of a liquid decreases with increasing atmospheric pressure
The vapor pressure of a liquid does not decreases with increasing atmospheric pressure. The vapor pressure of a liquid is independent of the atmospheric pressure. The vapor pressure of a liquid depends on the nature of the liquid and the temperature.

Q. Statement - I
A cylinder fitted with a movable piston contains a certain amount of liquid in equilibrium with its vapor. The temperature of the system is kept constant. If the volume of the vapor is decreased by moving the piston inwards, the vapor pressure will remain unchanged.
Statement - II
Vapor, in equilibrium with its liquid, at constant temperature does not obey Boyle's law.
