Correct option is (a) Directly proportional

Explanation: The boiling point relates to the temperature when the vapor pressure of the liquid equals the surrounding environmental pressure. Thus, the boiling point is dependent on the pressure. The boiling point increases with increase in the pressure up to the critical point.
