Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes.
At high elevation than sea level surrounding pressure is low so that boiling point of water becomes low.
