Protein is essential to the overall health of the body because it a. bulk up muscles b. keeps hair and nails healthy c. gives the body collagen, which protect the organs d. sustains life and keeps body systems in good repair

Hello,

The answer is option D sustains life and keeps body systems in good repair.

Reason:

The answer is D because protein is very important to the body because it fuels your body without protein you wouldn't be able to live. Its not option A because protein does not help you build muscles. Its not option B it doesn't keep your nails or your hair. Its also not C because protein gives energy not collagen.

If you need anymore help feel free to ask me!

Hope this helps!
