Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Boiling point is the point where vapour pressure becomes equal to the atmospheric pressure. Water boils below 100 $^{0}$ C on top of Mount Everest because the boiling point is directly proportional to the atmospheric pressure.

At the top of the Mount Everest, the pressure is minimum, so the boiling point will be decreased.

Thus, Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Hence, the correct option is $A$ .
