Reflex arc comprises of:
Correct answer: C. Both Aand B
- A. Motor nerve
- B. Sensory nerve
- C. Both Aand B
- D. Mixed nerve
Explanation
Each sensory neuron conveys a signal, from a sensory receptor to a motor neuron, which in turn sending signals to an effector the result is often a simple, automatic response called a reflex or reflex action.Thus,reflex arc comprises of sensory and motor neurons.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
