Answer:

C. The insertion is where a muscle attaches to the bone it wants to move

Explanation:

Skeletal muscles produce the movement by exerting force on tendons which in turn pull on the bones. Tendons are the connective tissues that serve to attach muscles to the bones. Muscle attachment site on bones are called as origin and insertion. Origin is the attachment site of muscles's tendon to the bone which is not in moving position. Other tendons of the muscle become attached to a movable bone; this attachment site is called as insertion.
