Which of the following have least Albedo?

Solution (By Examveda Team)

Albedo is the measure of reflectivity, the amount of sunlight reflected by any surface. All the black surfaces have the lowest albedo as they reflect the least amount of radiation and absorb most of the radiation. Because moist black soil absorbs the most light of all the black soils, it has the lowest albedo. The highest albedo is found in snow-covered areas and deserts.
