The theory that suggests that cells in the visual system respond in excitatory/inhibitory pairs, such as red/green or blue/yellow is the opponent-process theory.

Here's a step-by-step explanation:

1. The trichromatic theory suggests that there are three types of color receptors in the eye, which are sensitive to different color wavelengths. This theory doesn't involve the concept of excitatory/inhibitory pairs.

2. The opponent-process theory, on the other hand, proposes that our color perception is controlled by three opposing pairs: red/green, blue/yellow, and black/white. This means that when one member of a pair is activated, the other is inhibited. So, this is the theory that suggests cells in the visual system respond in excitatory/inhibitory pairs.

3. The dual-process theory is a psychological model that suggests that two different psychological processes are responsible for a person's cognitive and behavioral reactions. It's not related to color perception.

4. The adaptation theory is a broad term that can refer to various theories in different fields, including biology, psychology, and sociology. In the context of vision, it might refer to how our eyes adjust to different light conditions, but it doesn't involve the concept of excitatory/inhibitory pairs.

So, the correct answer is the opponent-process theory.
