What takes place at the synapse? Neurotransmitter molecules travel across the synaptic cleft and bind to receptors on the membrane of the other cell.
Neurotransmitter molecules travel across the axon terminals and bind to receptors on the membrane of the other cell.
Neurotransmitter molecules travel across the axon terminals and bind to vesicles on the membrane of the other cell.
Neurotransmitter molecules travel across the synaptic cleft and bind to signal proteins on the membrane of the other cell.

i think At a chemical synapse, one neuron releases neurotransmitter molecules into a small space (the synaptic cleft) that is adjacent to another neuron. The neurotransmitters are contained within small sacs called synaptic vesicles, and are released into the synaptic cleft by exocytosis.

Explanation: i hope this answer your question

The most commonly found synapses in humans are chemical synapses. This occurs due to electrical activity in the presynaptic neurons triggering the release of neurotransmitters.

The neurotransmitters disperse across the synaptic cleft to then bind themselves to specialized receptors of postsynaptic neurons. Once this occurs, the neurotransmitters then either excites or inhibits the postsynaptic neuron. Exciting the postsynaptic neuron leads to a firing of action potential (electrical impulses), whereas inhibiting the postsynaptic neuron prevents the transmission of a signal.

i think it’s c but i might be wrong. if i am let me know! have a good rest of your day as well!
