Which one of the following muscles are considered as "Voluntary muscles"?

Explanation

Functionally, our body has three categories of muscles i.e. Smooth, Cardiac, and Skeletal which are then further classified as voluntary and involuntary muscles. Voluntary muscles are muscles under conscious control i.e. they be controlled at will or we can choose when to use them. A good example of voluntary muscles is skeletal muscles which are responsible for the movement of body parts and locomotion. Hence, Option C is correct. On the other hand, involuntary muscles are those which are not under our conscious control. Examples of involuntary muscles include Smooth and Cardiac Muscles. Cardiac muscles contract on their own due to the self-excitable SA Node. Similarly, smooth muscles like glandular muscles contract automatically and release hormones when required.
