Answer: (D)

Verified step by step guidance

1. Understand that an action potential is an electrical signal that travels along the axon of a neuron.
2. Recognize that when the action potential reaches the end of the axon, it arrives at the axon terminal.
3. At the axon terminal, the action potential triggers the release of neurotransmitters into the synaptic cleft, the gap between neurons.
4. These neurotransmitters bind to receptors on the adjacent neuron, which can initiate a new action potential in that neuron.
5. This process of neurotransmitter release and binding allows the message to be transmitted from one neuron to another, continuing the communication pathway in the nervous system.
