The correct answer to this question is A, Snow. Albedo is a type of measurement, and Johann Heinrich Lambert introduced the idea of it. It is used to measure solar radiation's diffuse reflection. It has no dimension and is measured on a scale from 0 to 1.

A high albedo means a high amount of radiation is reflected on the surface, and not much is absorbed. Snow is the highest because it reflects about 95% of radiation. Albedo is an essential measurement in fields such as astronomy and climatology. Though not as high as snow, other surfaces that have high albedo include ice, sand, and soil.

Are you familiar with the term albedo? If you answer no, you may not understand how to answer this question. Albedo refers to the energy from the sunlight that comes back to the atmosphere. There are certain items that may have lower or higher albedo depending on how they would reflect the sun’s rays.

From the given, the one with the highest albedo is snow which means that A is the right answer. Snow is normally white and it has the tendency to reflect the rays of the sun. This means that there will be more energy that will be cast back to the atmosphere when it hits snow as compared to the two other choices.
