    Option B is correct

    Explanation:

    Step 1: Define volatility

    In chemistry, the term volatility, is a way to describe how readily a substance transitions from a liquid phase to a gas phase, also called evaporating.

    At a given temperature and pressure, a substance with high volatility is more likely to evaporate more quickly, while a substance with a lower volatility is more likely to be a liquid or solid, so not to evaporate or slower.

    The higher the volatility, the higher the (vapor) pressure of a compound. Increasing temperature means the vapor pressure will also increase,

    Step 2: In this case:

    ⇒ Option A is false because the pressure will be higher when volatility is higher.

    ⇒ Option B is correct because higher volatility means evaporating more quickly

    ⇒ Option C is false because higher volatility means higher pressure. When pressure increases, the surface tension decreases.

    ⇒ Option D is false because when the volatility is higher, the liquid/gas escape the container, easier, so there will be less resistance.
