Diagram A below shows a stimulus applied to a sensory cell, and diagram B is the pattern of action potentials generated in response. This pattern of action potentials:

A)permits discrimination between different kinds of stimuli.
B)improves the simultaneous detection of two kinds of stimuli-for example, smell and taste.
C)allows an animal to constantly measure the strength of a continuing input.
D)allows an animal to detect the onset of a new stimulus. /12
