Answer

An example of a multipennate muscle is the deltoid.

Explanation:

• Multipennate muscles are characterized by the arrangement of their fibers, which are structured like multiple feathers that insert into a central tendon.
• The deltoid muscle, located in the shoulder, exhibits this form as it has several bundles of muscle fibers that converge to attach to the upper arm bone (humerus).
• Other options listed, such as the rectus femoris and pectoralis major, are not classified as multipennate, although the extensor digitorum longus is a unipennate muscle.

Therefore, the correct choice among the options provided is the deltoid muscle.
