**Core Concept:** The retina is a part of the vertebrate eye that processes light and converts it into electrical signals. Neurons in the retina play a crucial role in vision, and the location of their cell bodies can help identify their specific functions.

**Why the Correct Answer is Right:** The correct answer is Option C: Ganglion cells. Ganglion cells are a type of neuron found in the retina, and their axons, known as the optic nerve, extend beyond the eye and form the optic nerve. These neurons are responsible for transmitting visual information from the retina to the brain, specifically to the brain's visual center, the lateral geniculate nucleus (LGN) in the thalamus.

**Why Each Wrong Option is Incorrect:**

A. Amacrine cells: Amacrine cells are also retinal neurons, but they are interneurons, meaning they do not have axons that leave the retina. Their cell bodies are located in the inner nuclear layer (INL).

B. Photoreceptor cells: Photoreceptor cells are the light-sensitive neurons responsible for detecting light and dark. Their cell bodies are located in the outer nuclear layer (ONL).

D. Horizontal cells: Horizontal cells are another type of retinal interneuron that helps in processing visual information. Their cell bodies are located in the inner nuclear layer (INL).

**Clinical Pearl:** Understanding the location of retinal neurons is crucial for understanding visual pathways and the initial stages of vision processing. This knowledge is essential for diagnosis and treatment of vision-related disorders.

**Correct Answer:** The cell bodies of Ganglion cells are located in the **inner nuclear layer (INL)**. These neurons play a vital role in transmitting visual information from the retina to the brain, specifically to the brain's visual center, the lateral geniculate nucleus (LGN) in the thalamus.
