Which of the following correctly describes neurotransmission?

A. An action potential travels down the axon and triggers the release of
neurotransmitters. The neurotransmitters cross the synapse, and another action
potential begins.

B. A neurotransmitter travels down the axon and triggers the release of an action
potential. The action potential crosses the synapse, and another
neurotransmitter begins.

C. The synapse travels down the axon and triggers the release of an electrical
impulse. The electrical impulse crosses the neurotransmitter, and another
synapse begins.

D. A neuron sends a chemical signal down its axon. The axons touch the dendrites of
another neuron, and the signal continues.
