D. Axons

Answer

**Step-by-Step Solution:**

1. **Understanding the Nervous System**: The nervous system is divided into two main components: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS consists of nerves that extend throughout the body.

2. **Identifying the Structure of Nerves**: Nerves are part of the peripheral nervous system. They are essential for transmitting signals between the CNS and the rest of the body.

3. **Composition of Nerves**: Nerves are made up of bundles of axons. Axons are the long, thread-like parts of neurons that carry electrical impulses away from the neuron's cell body.

4. **Conclusion**: Therefore, a nerve is defined as a bundle of axons.

**Final Answer**: A nerve is a bundle of axons.
