Correct Option a) Both assertion and reasoning are true, and reasoning is the correct explanation of the assertion.

At higher altitudes, the atmospheric pressure decreases. As a result, the boiling point of water decreases because the pressure on the liquid decreases, and it requires less energy to change into vapour. This is the reason why water boils at a higher temperature at higher altitudes.

So, both the assertion and reasoning are true, and reasoning is the correct explanation of the assertion.
