A) Receiving is to sending

There often many dendrites per neuron, but only one axon. dendrites branch in many directions and are sensitive to signals from other neurons. They receive these signals and pass them to the soma (the part of the neuron that contains the nucleus). It is the axon that sends these signals to other neurons.
