Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Water has a high specific heat index. It absorbs a lot of heat before it begins to get hot. This is why water is valuable to industries and in car's radiator as a coolant. The high specific heat index of water also helps regulate the rate at which air changes temperature, which is why the temperature change between seasons is gradual rather than sudden, especially near the oceans. Thus, the correct answer is option A.
