Answer
The correct answer is **a. 86%**.Here's why:The Earth's surface is about 71% water. Water is a very effective absorber of solar radiation. While some solar energy is reflected by clouds, ice, and other surfaces, the vast majority of the solar energy that reaches Earth is absorbed by the oceans. Estimates vary slightly, but around 86% is a commonly accepted figure for the portion of incoming solar radiation absorbed by water (including oceans, lakes, rivers, etc.). The other options are far too high. No percentage of absorption can be over 100%, as that would imply more energy is absorbed than arrives.
