**Core Concept**
Facial muscles are derived from the second pharyngeal arch, also known as the hyoid arch. This arch is responsible for the development of various structures, including the muscles of facial expression. The second pharyngeal arch is a critical component of embryonic development, giving rise to several important facial features and functions.

**Why the Correct Answer is Right**
The facial muscles, including the orbicularis oculi, zygomaticus major, and orbicularis oris, are innervated by the facial nerve (cranial nerve VII). The facial nerve originates from the second pharyngeal arch and is responsible for controlling the muscles of facial expression. During embryonic development, the second pharyngeal arch gives rise to the muscles of facial expression, which are essential for facial movements such as smiling, frowning, and facial expressions.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the first pharyngeal arch is primarily responsible for the development of the muscles of mastication, including the masseter, temporalis, and medial pterygoid muscles.
**Option B:** This option is incorrect because the third pharyngeal arch is responsible for the development of the muscles of the neck, including the sternocleidomastoid and trapezius muscles.
**Option C:** This option is incorrect because the fourth pharyngeal arch is responsible for the development of the muscles of the larynx and pharynx.

**Clinical Pearl / High-Yield Fact**
It is essential to remember that the facial nerve (cranial nerve VII) is responsible for controlling the muscles of facial expression, and damage to this nerve can result in weakness or paralysis of these muscles, leading to conditions such as Bell's palsy.

**Correct Answer: C. Muscles of the second pharyngeal arch, also known as the hyoid arch.**
