Solution
The correct option is D Long wave radiation
The earth receives energy from the sun in the form UV, visible, and near IR radiation, most of which passes through the atmosphere without being absorbed or reflected. Of the total amount of energy available at the top of the atmosphere, about 26% is reflected back out to space by the atmosphere and clouds via evapotranspiration which ultimately radiates the energy in the form of long wave radiations. Most of the remaining energy is absorbed in the earth's surface by greenhouse gasses. Because it is warm leads to a higher temperature of the earth. Thus, the correct answer is option B.
