Fiona puts her hands into a sinkful of lukewarm water; Luke puts his hands into a sinkful of ice-cold water. What should we predict about each of their action potentials?

B) Luke's will travel a shorter distance because the stimulus is more intense.
C) Their action potentials will be the same due to the all-or-none principle.
D) Their action potentials will be distinguished by the amount of inhibition.
