Final answer:
Complex cells respond best to moving stimuli, as their advanced sensory systems are designed to detect environmental changes critical for survival, such as navigating and locating resources.
Step-by-step explanation:
Unlike simple cells, complex cells respond best to B) Moving stimuli. Complex cells have developed sophisticated systems to detect and respond to various environmental changes. Unlike plants that show growth movements toward light or can respond to touch, complex cells, such as those found in the animal nervous system, are especially attuned to changes in their environment, including movement. For example, certain nerve cells called photoreceptors can detect changing light patterns as motion. This sensitivity to moving stimuli is critical for many organisms to navigate, find food, and avoid predators.
