In which situation is it necessary to understand the complete pathway of control and coordination?
Answer and explanation
Correct answer: When the receptor works correctly but the effector does not respond
A coordinated response normally follows a pathway: a receptor detects a stimulus, a sensory route carries information to a coordinating centre, and a motor route activates an effector. If the receptor works but the effector fails, the pathway must be analysed to locate the breakdown, so option A is correct. Merely memorising a hormone name does not require pathway analysis, and options C and D do not describe a meaningful control-and-coordination problem.
