Answer:
C. Stimuli presented below the absolute threshold can have a subtle, brief effect on behavior.
Explanation:
The absolute threshold is simply the stimulation necessary for a stimulus to cause a specific sensation, such as light, sound, taste, pressure, or odor 50% of the time.
Despite being considered a limiting factor, it is possible to perceive stimuli below the absolute threshold. Because it is a point where we detect a stimulus half of the time, so exactly at the threshld or below it, it is still possible to detect a stimulus eventually.
