This sequence refer to how neurons send messages electrochemically. When the neurons are at rest, they are at its resting potential at - 70 millivolts. If the neurons in the brain send messages, a spike would occur until it reaches the threshold potential at - 55 mV. If it reaches the threshold potential, then an action potential occurs. Hence, the sequence would be letter C.
