Which of the Following Correctly Describes Divergence

Which of the following correctly describes divergence?

A) Thousands of synapses from many presynaptic neurons end on a single postsynaptic cell.
B) The dendrites diverge from the cell body to contact as many presynaptic neurons as possible.
C) The action potential initiated in the axon diminishes as it diverges into the axon terminals.
D) The axon of a nerve cell branches to synapse with many other cells, so that activity in one neuron influences the excitability of many other cells.
For the following questions, assume a hypothetical postsynaptic neuron has three presynaptic inputs: X, Y, and Z. Also assume that presynaptic neurons Y and Z are excitatory.
