Which of the following is consistent with the "all-or-none" law?
A) The action potential will diminish to near 0 mV when transmitted down a long axon.
B) The action potential fires at the same rate regardless of the inputs to the neuron.
C) The action potential is conducted more rapidly down the axon as it reaches the axon terminal.
D) The action potential is produced whenever the membrane potential reaches threshold.
E) The action potential travels only in one direction.

According to the "all-or-none" law, the action potential is produced whenever the membrane potential reaches threshold. This means that once the threshold is reached, the action potential is always of the same amplitude and duration, regardless of the strength of the stimulus that caused it. Therefore, the option D is consistent with the "all-or-none" law. Options A, B, C, and E are not consistent with the "all-or-none" law.
