A. The total amount of energy received by the earth is sent back as ame amount by losing it to space.

Explanation:

Earth only receives a fraction of sunlight in the form of electromagnetic radiation. As 100 % energy comes from sun of which 50 % is absorbed by the earth features, land sea, and oceans. 20% is absorbed by the clouds and the atmosphere, and 30% is reflected by clouds making earth albedo of 35 %. This occurs 24 hr a day and is carried out in long wave terrestrial radiation. As compared to short term solar radiation.
