**Core Concept**
The question is testing the student's knowledge of the facial nerve's function in controlling the lacrimal gland, which produces tears for eye lubrication. The facial nerve's involvement in tear production is crucial for maintaining eye health and preventing dryness.

**Why the Correct Answer is Right**
The facial nerve, also known as the seventh cranial nerve, has a parasympathetic branch that controls the lacrimal gland, promoting tear production. This branch is responsible for the lacrimal gland's secretory function, ensuring that the eyes remain moist and lubricated. When the facial nerve is injured, the lacrimal gland's ability to produce tears is compromised, leading to dryness of the eye.

**Clinical Pearl / High-Yield Fact**
The facial nerve's involvement in tear production is essential for maintaining eye health. Injury to the facial nerve can lead to a condition called dry eye syndrome or keratoconjunctivitis sicca, characterized by reduced tear production and eye dryness.

**Correct Answer:** C.
