Question

which pathway(s) compose the autonomic nervous system? cns pns a b c a only b only c only

Explanation:

The autonomic nervous system (ANS) uses a two - neuron pathway (preganglionic and postganglionic neurons). Option A shows a single - neuron pathway (somatic nervous system, like motor neurons to skeletal muscle). Option B has a synapse in the PNS (ganglion), indicating a two - neuron ANS pathway. Option C's synapse location or structure doesn't fit typical ANS; the ANS has preganglionic (CNS - to - ganglion) and postganglionic (ganglion - to - effector) neurons, which matches B.

Answer:

B only
