Neuron X makes inhibitory axon-axonal synaptic contact with neuron Y at the synapse of Y and neuron Z. Which will occur when action potentials are stimulated in neuron X?

A、Neuron Y will be inhibited from reaching the threshold to fire an action potential;

B、The release of neurotransmitter by neuron Y will be inhibited;

C、The synapse between neurons Y and Z will be changed from an excitatory synapse to an inhibitory one;

D、Neurons Y and Z will both be more likely to reach threshold and fire an action potential;

E、Neurons Y and Z will both be less likely to reach threshold and fire an action potential
