Answer & Solution

Answer: (Detailed Solution Below)

Option C: Land covered with fresh snow

Detailed Solution:

The correct answer is “Land covered with fresh snow”.

Land covered with fresh snow reflects back more sunlight compared to the other three options.

Snow is highly reflective due to its white color, which absorbs very little sunlight and instead reflects most of it back into the atmosphere. This is why snow-covered areas can appear so bright and can contribute to the overall albedo of the Earth, affecting its climate.
