Explanation / Answer

(19) An increase in pressure increases the boiling point of the liquid. A liquid boils faster at higher altitudes as the pressure at higher altitude is lesser, on the other hand, the same liquid will boil at a higher temperature at sea level because the pressure at sea level is higher.

The correct answer is the option (a).
