Answer: (B)

Verified step by step guidance

1. Identify the key function of neurons in the nervous system, which is communication between different parts of the body.
2. Understand that neurons communicate by sending signals, and these signals are electrical in nature.
3. Recognize that the electrical signals generated and transmitted by neurons are called action potentials.
4. Recall that action potentials allow neurons to rapidly transmit information over long distances within the nervous system.
5. Conclude that the characteristic of neurons that best explains their communication ability is their capacity to generate and transmit action potentials.
