Question

Quizplus · Accepted Answer

Both options A and B involve color having a signaling function. A ripe banana is signaled by its yellow color, and the color of a traffic light signals drivers to stop (red) or go (green). Therefore, choice C is the correct answer. Choice D is incorrect because signaling is indeed a function of color.
