Correct Answer: Option A
Explanation

The vapor pressure of any substance increases non-linearly with temperature, often described by the Clausius–Clapeyron relation.

As the temperature of a liquid or solid increases its vapor pressure also increases.

Conversely, vapor pressure decreases as the temperature decreases. 

i.e. vapor pressure is directly proportional to temperature

There is an explanation video available below.
