**Core Concept**
Colour vision involves the detection and interpretation of light by specialized photoreceptor cells in the retina, specifically cone cells, which contain pigments sensitive to different wavelengths of visible light. The primary pigments responsible for colour vision are cone opsins, which are embedded in the cone cells.

**Why the Correct Answer is Right**
The correct answer is likely to involve a structure or process not directly related to colour vision. However, since the options are not provided, I'll explain the typical components involved in colour vision. The S-cones are sensitive to short-wavelength (blue) light, while M-cones are sensitive to medium-wavelength (green) light, and L-cones are sensitive to long-wavelength (red) light. The signals from these cones are interpreted by the brain to perceive colours.

**Why Each Wrong Option is Incorrect**
Since the options are not provided, I'll explain how to evaluate distractors in general:
* **Option A:** If A involves a structure or process directly related to colour vision, such as cone opsins or the retina, it is likely incorrect.
* **Option B:** If B involves a visual pathway or process not directly related to colour vision, such as the optic nerve or visual cortex, it is a plausible distractor.
* **Option C:** If C involves a structure or process involved in colour vision, such as the fovea or macula, it is likely incorrect.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that colour vision deficiency (colour blindness) is usually inherited in an X-linked recessive pattern, affecting males more frequently than females due to the presence of one X chromosome.
