The correct answer to this question is A, Skeletal Muscle. There are three main types of muscles in the body, and skeletal muscle is one of them. The other two are the cardiac and smooth muscles. Skeletal muscles are voluntary. The skeletal muscle controls an action a person does. There are two types of skeletal muscles.
The first is a slow-twitch. This muscle contains proteins that make it bright red. The second is a fast-twitch, which has a white color because it has less protein. The slow-twitch is used for long-distancesports like running. The fast-twitch is used for anaerobic exercise like sprinting
