Answer 1

The correct option is C They show a pattern of cross-banding.

Skeletal muscles are those, which attach to bones and have the main function of contracting to facilitate movement of the skeletons. They are also sometimes known as striated muscles due to their appearance. The cause of this stripy appearance are the bands of actin and myosin, which form the sarcomere, found within the myofibrils.
