Solution
The correct option is B Albedo
A part of the solar radiation falling on any surface is reflected back. Thus a certain amount of energy is lost and it does not play any role in heating the atmosphere. The reflectivity of a substance usually expressed as a percentage of the incident radiation reflected is known as it's albedo or reflection coefficient. It differs from place to place as well as from time to time.
