Why Neuron A is a healthy neuron

Neuron A is a healthy neuron with all the usual ion channels.  When at rest with a membrane voltage of R millivolts, neuron A produces no action potentials.  The voltage threshold for an action potential in neuron A is T millivolts.  T is greater than R; T is less than zero.  In addition, neuron A's membrane includes the membrane-spanning molecule Z with an ion channel that opens when neurotransmitter Y binds to the Y receptor site on the extracellular surface of Z.  The Nernst equilibrium potential for Z's ion channel is E millivolts.  Neuron B synapses on neuron A; neuron B's neurotransmitter is neurotransmitter Y.  Which of the following statements are true when neuron A is initially at rest and neuron B releases neurotransmitter Y?

  A.  If the value of E is equal to R, and if chloride is the only ion that passes through open Z channels, then Y's binding to its receptor site on Z in neuron A produces no change in the amount of intracellular chloride ions in neuron A.

  B.  If the value of E is equal to R, and if chloride is the only ion that passes through open Z channels, then Y's binding to its receptor site on Z in neuron A produces no change in the chloride conductance of the plasma membrane of neuron A.

  C.  If the value of E is zero and if both sodium ions and potassium ions pass through open Z channels, then Y's binding to its receptor site on Z in neuron A produces no change in the amount of intracellular sodium ions in neuron A.
