The All-Or-None Law of Neural Conduction Suggests That ___________

The all-or-none law of neural conduction suggests that ___________.

A) all neurons have action potential thresholds but none of them are the same threshold
B) if the action potential threshold is just met, a weak action potential will occur whereas if the action potential threshold is exceeded, a more intense action potential will occur
C) once the action potential threshold is met, an action potential of uniform and maximum intensity occurs
D) once an action potential has occurred, the neuron will either take all or none of the refractory period time before firing another action potential
