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.

The answer would be the muscle fiber because it's the small part of the contracting unit.
