Madeleine Riggs · Answer 1

is A.

Explanation:

When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated Na + channels. Na + ions enter the cell, further depolarizing the presynaptic membrane ... Fusion of a vesicle with the presynaptic membrane causes neurotransmitters to be released into the synaptic cleft.
