Answer: (A)

Verified step by step guidance

1. Understand the purpose of the visual cliff experiment, which is designed to test an infant's ability to perceive depth and judge distances.
2. Recognize that depth perception is the ability to see the world in three dimensions and to judge how far away objects are, which is crucial for navigating the environment safely.
3. Note that auditory discrimination involves distinguishing between different sounds, which is unrelated to the visual cliff setup.
4. Acknowledge that color vision refers to the ability to perceive different colors, which the visual cliff does not specifically test.
5. Understand that object permanence is the cognitive understanding that objects continue to exist even when they cannot be seen, which is tested by different experiments, not the visual cliff.
