**Core Concept**
Accommodation in the eye refers to the process by which the lens changes shape to focus on near objects. This is achieved through the contraction of the ciliary muscles, which increases the curvature of the lens. The ciliary muscles are innervated by the parasympathetic division of the autonomic nervous system.

**Why the Correct Answer is Right**
The ciliary muscles are responsible for accommodation by contracting and relaxing to change the shape of the lens. This process is mediated by the parasympathetic division of the autonomic nervous system, specifically through the ciliary ganglion and the short ciliary nerves. These nerves release acetylcholine, which stimulates the contraction of the ciliary muscles.

**Why Each Wrong Option is Incorrect**
**Option A:** The nerves passing through the **optic nerve** are responsible for transmitting visual information from the eye to the brain, not for accommodation.
**Option B:** The **oculomotor nerve** is responsible for controlling the movement of the eye, including adduction, abduction, and elevation, but not for accommodation.
**Option C:** The **trigeminal nerve** is responsible for sensory innervation of the face, including the eye, but not for accommodation.

**Clinical Pearl / High-Yield Fact**
The ciliary muscles are responsible for accommodation, and their contraction is mediated by the parasympathetic division of the autonomic nervous system. This is why mydriatic agents, such as tropicamide, can cause a loss of accommodation.

**Correct Answer:** D.
