Neurons A, B, C, D, and E synapse with Neuron F. Neurons A, C, and E are inhibitory, and neurons B and D are excitatory. If neurons B and D are activated but neurons A, C, and E are not, what is most likely to happen to Neuron F?
A) It will fire because Neurons B and D will release transmitter substances that will excite its postsynaptic membrane.
B) It will not fire, because it is inhibited by Neurons A, C, and E.
C) It will remain at rest because all neurons need to be stimulated by at least three other neurons in order to fire.
D) It will fire because activation of Neurons B and D will cause the ion channels in it to open and let in positively charged potassium ions.
E) It will not fire because all neurons, both inhibitory and excitatory, must be activated in order for a synapse to occur.

Since neurons B and D are excitatory and are activated while the inhibitory neurons A, C, and E are not, Neuron F is more likely to fire due to the excitatory influence of neurons B and D.
