Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The velocity of sound in a gas is directly proportional to the square root of its absolute temperature ( $v = \sqrt{\frac{ρ R T}{M}}$ ). Since, temperature of a hot day is more than cold winter day, therefore sound would travel faster on hot summer day than on a cold winter day.
