\(B\)

Show Worked Solution
  • B is correct: Motor neurons in the peripheral nervous system receive messages from the central nervous system and connect with effectors (muscles) to carry out the response.

Other Options:

  • A is incorrect: Detecting environmental stimuli is the function of sensory receptors and sensory neurons.
  • C is incorrect: Processing sensory information is primarily done by interneurons in the central nervous system.
  • D is incorrect: Carrying signals from muscles to the CNS is the function of sensory neurons, not motor neurons.
