If a pebble is tossed into a pond, it generates small ripples that decrease in size as the ripples move away from the point where the pebble struck the water. The decreasing size of the ripples as they move away from the initial splash is most like the way that signals spread ________.
A) in a graded potential
B) in an action potential
C) during hyperpolarization
D) during depolarization

Graded potentials decrease in strength as they move away from the point of stimulus, similar to how ripples decrease in size as they move away from where the pebble was tossed into the pond. Action potentials, on the other hand, maintain their strength as they travel along the neuron.
