Solution

The neuron that delivers signals from the eye to the thalamus of the brain is:

b. Ganglion cells

Explanation:

Ganglion cells are the output neurons of the retina. They receive input from bipolar cells, which in turn receive signals from photoreceptors (rods and cones). The axons of ganglion cells form the optic nerve, which carries visual signals from the retina to the thalamus, specifically to the lateral geniculate nucleus (LGN). The LGN then sends these signals to the visual cortex of the brain for processing.

In contrast, bipolar cells transmit signals from photoreceptors to ganglion cells, amacrine cells and horizontal cells are involved in local processing of visual information within the retina, and photoreceptors detect light but do not send signals directly to the brain. Therefore, among the given options, ganglion cells are the correct choice for delivering signals from the eye to the thalamus.
