C

Explanation:

Firstly, an action potential travels down to an axon and reaches the presynaptic membrane. After that synaptic vesicles move to and bind with the presynaptic membrane. Than, neurotransmitters are released into the synaptic cleft. In the next step, receptors on the postsynaptic membrane bind the neurotransmitters. In the last step, binding neurotransmitters cause excitation or inhibition.
