Quizplus · Accepted Answer

Muscle labeled D is located between the deltoid and pectoralis muscles, which are covered by fascia. Therefore, the origin of the muscle is the fascia over these muscles (option B). The other options (fascia over parotid gland, skin of lower lip, epicranial aponeurosis, and mandible) are not related to the location of muscle D.
