You Stimulate a Neuron Response by Adding a Given Amount

You stimulate a neuron response by adding a given amount of excitatory neurotransmitter mixed with a 6x higher concentration of an inhibitory neurotransmitter to the synaptic cleft. You expect that

A) as a result of neuronal integration, there will be an inhibitory signal.
B) excitatory responses will travel 1/6 as often as inhibitory ones.
C) as a result of neuronal integration, there will be an excitatory signal.
D) the neuron will be confused and will not respond to the signal.
E) inhibitory responses will travel 1/6 as often as excitatory ones.
