It makes a synapse and can also be post-synaptic to synapses. The
issue is that it does not generate action potentials. I don't
believe there is clear consensus on what to call it - it depends
upon how you define a neuron.

The hair cell works with graded potentials that determine the
release of neurotransmitter, so it is your option A.
