Which layer contains the cell bodies of photoreceptors?

Explanation:
Photoreceptors—the rods and cones—have their cell bodies in the outer nuclear layer. This layer houses the nuclei of the photoreceptor cells, while their inner segments and synaptic connections are arranged toward adjacent layers. The outer plexiform layer, just inner to that, is where photoreceptors form synapses with bipolar and horizontal cells. In contrast, the inner nuclear layer contains the nuclei of bipolar, horizontal, and amacrine cells, and the ILM marks the innermost boundary of the retina with the vitreous.
