"WebAlbedo values are a measure of how well a surface reflects light; The values of various substances differ accordingly. This clearly shows that the albedo of all black surfaces is the lowest. Fresh snow has the highest albedo since it reflects nearly all of the sun's rays. Therefore, option (a) is the correct answer. " - Snow albedo definition
