Which of the following absorbs the insolation from the sun and preserves the earth's radiated heat, thus acting like a blanket allowing the earth neither to become too cold nor too hot?

Solution (By Examveda Team)

Water vapour absorbs parts of the insolation from sun and thus reduces its amount. It also preserves the earth's radiated heat. It thus acts like a blanket allowing the earth neither to become too cold nor too hot.
