Solution

The correct option is D By decreasing the pressure on the liquid
The liquid boils at the temperature when the vapor pressure becomes equal to the atmospheric pressure. So by decreasing the pressure on the liquid, boiling point of the iquid is reduced.
For example : water boils at lower temperature at high altitudes.
