Final answer:
The efferent neurons in the autonomic nervous system are arranged in preganglionic and postganglionic neurons, which synapse in ganglia near the spinal cord or target organs and then innervate effector organs.
Step-by-step explanation:
The arrangement of efferent neurons in the autonomic nervous system is described by the terms preganglionic and postganglionic.
In the sympathetic division, preganglionic neurons are found in the thoracic and lumbar regions of the spinal cord, and their axons synapse with postganglionic neurons in ganglia near the spinal cord. Postganglionic neurons then innervate effector organs.
In the parasympathetic division, preganglionic neurons are found in the cranial and sacral regions of the spinal cord, and their axons synapse with postganglionic neurons in ganglia near or within the target organs. Postganglionic neurons then innervate effector organs.
Therefore, the correct answer is: c) Preganglionic, Postganglionic, Peripheral.
