Explanation:

To solve this, we analyze each option:

• Tracts: Bundles of axons in the central nervous system (CNS), not cell bodies outside CNS. Eliminate.
• Nuclei: Collections of nerve cell bodies within the CNS. Eliminate.
• Ganglia: Defined as collections of nerve cell bodies outside the CNS. This matches the question.
• Nerves: Bundles of axons (with associated cells) in the peripheral nervous system, not just cell bodies. Eliminate.
