The Correct Option is B
Solution and Explanation
The ratio of the total solar radiant energy reflected by a planetary body to the total solar radiant energy incident on it is called albedo. It is a measure of the reflectivity of a surface. Reflectance factor is a similar concept but often refers to specific wavelengths and viewing geometries. Diffraction is the bending of waves around obstacles, and refraction is the bending of waves as they pass from one medium to another.
