D

The vesicle release of two particular pre-synaptic neurons results in an action potential firing in a postsynaptic neuron. When the vesicle release of an additional third pre-synaptic neuron is added to this circuit, no action potential is triggered in the postsynaptic neuron. Why might this be the case? A) Vesicle release from the third pre-synaptic neuron depolarizes the postsynaptic neuron, moving it away from the action potential threshold. B) Neurotransmitters released from the third pre-synaptic neuron, bind to receptors on the postsynaptic cell, opening sodium channels. C) The negatively charged neurotransmitters released from the third pre-synaptic neuron enter and hyperpolarize the post-synaptic neuron. D) Activity of the third pre-synaptic neuron results in the opening of chloride channels on the postsynaptic neuron, thus leading to hyperpolarization.
