Which option gives the three main roles of the nervous system in a correct order?
Answer and explanation
Correct answer: Detecting stimulus, carrying message and producing response
The nervous system coordinates responses through a sequence: receptors first detect a stimulus, sensory neurons carry information to the central nervous system, and motor pathways activate an effector. The effector then produces the response. Thus option A gives the correct order. The remaining choices list functions of plants, kidneys, bones, or imaginary processes rather than the three main nervous-system roles.
