While some contact lenses provide UV protection, they don't cover your whole eye, so you still need sunglasses. Look for sunglasses that protect you from 99 to 100 percent of both UVA and UVB light. This includes those labeled as "UV 400," which blocks all light rays with wavelengths up to 400 nanometers.

klasskru [66]
The answer to this question would be  <span>A.) It provides energy and fights infections.

The nutrient is a substance that needed to maintain life. This included carbohydrate which gives most energy, an amino acid that makes protein and used for making cells, or vitamin for reaction coenzyme. 
The option in this question is not clear and I think all of them can be said as a benefit of nutrient. The option A is about carbohydrate, option B and C about protein/amino acid and option C about vitamin.
But the most vital need for an organism is energy, so I think A will be the best option if you need to choose only one.</span>
