Brightness constancy is most clearly facilitated by
A) proximity.
B) interposition.
C) relative luminance.
D) retinal disparity.
Relative Luminance
A measure of the amount of light that is reflected from or emitted by a surface, viewed from a specific angle, and normalized to a scale from 0 to 1.
Retinal Disparity
The slight difference in the visual images that reach each eye, which is then interpreted by the brain to gauge depth and distance.
Brightness Constancy
The perception of an object maintaining consistent brightness despite changes in the lighting conditions around it.

Final Answer :
C
Explanation :
Brightness constancy refers to our ability to perceive an object as having the same brightness even when its illumination changes. This is facilitated by relative luminance, which is the amount of light an object reflects relative to its surroundings. By considering the relative luminance of an object in its environment, our brains can adjust for changes in illumination and maintain the perception of its brightness. Proximity, interposition, and retinal disparity do not directly facilitate brightness constancy.
