- A. motor neurons
- B. interneurons
- C. autonomic nervous system
- D. central nervous system
Correct Answer: D
Rationale: Sensory neurons in the peripheral nervous system (PNS) transmit nerve impulses from sensory receptors (e.g., in the skin, eyes, or ears) to the central nervous system (CNS), which includes the brain and spinal cord. These neurons play a crucial role in detecting external and internal stimuli, such as touch, temperature, and pain, and relaying this information to the CNS for processing and response.
