Which of the following definitions best describes 'anterior auricular muscle'?

A. The the concept consists of two or three fleshy fasciculi, which arise from the mastoid portion of the temporal bone by short aponeurotic fibers. They are inserted into the lower part of the cranial surface of the concha.
B. The the concept, the smallest of the three auriculares muscles, is thin and fan-shaped, and its fibers are pale and indistinct. It arises from the lateral edge of the galea aponeurotica, and its fibers converge to be inserted into a projection on the front of the helix.
C. Is one of the numerus muscles of the external ear and is of importance since it is encountered in the operation for drainage of infections of the external ear of the dog. As its name suggests, it arises from the fascia over the parotid gland and approaches the auricle from the ventrolateral direction. This muscle is supplied by the facial nerve.The muscles of the external ear with their scattered origins and precisely located insertions provide for displacement and rotation of the ear in all directions. These muscles also have a collective function in communication both within and between species.
D. The the concept, the largest of the three auriculares muscles, is also thin and fan-shaped. Its fibers arise from the galea aponeurotica, and converge to be inserted by a thin, flattened tendon into the upper part of the cranial surface of the auricula.

Answer: The the concept, the smallest of the three auriculares muscles, is thin and fan-shaped, and its fibers are pale and indistinct. It arises from the lateral edge of the galea aponeurotica, and its fibers converge to be inserted into a projection on the front of the helix.
