Which option shows the complete process of control and coordination most correctly?
Answer and explanation
Correct answer: Detection of stimulus, transmission of message, decision and response by effector
The governing concept is the stimulus-response pathway of coordination. First, a receptor detects a change in the internal or external environment. The message is then transmitted to an integrating or control centre, which processes it and sends instructions to an effector such as a muscle or gland. The effector produces the response, so A is correct. B, C and D describe isolated or irrelevant events, not the complete pathway.
