Answer: (C)

Verified step by step guidance

1. Understand the concept of figure-ground perception, which is the ability to distinguish an object (the figure) from its surrounding background (the ground).
2. Recognize that depth perception refers to the ability to perceive the world in three dimensions and judge distances, which is different from distinguishing figure from background.
3. Know that color constancy is the ability to perceive colors of objects as relatively constant under varying illumination conditions, not related to figure-ground distinction.
4. Visual acuity refers to the sharpness or clarity of vision, which is about detail resolution rather than separating figure from background.
5. Conclude that the ability to distinguish an object from the background is specifically defined as figure-ground perception.
