Solution

The correct option is D
Receptors → Sensory neuron→ Spinal cord→ Motor neuron→ Muscle

The correct option is D.
Explanation of correct option:
It is a special type of neural circuit that controls the reflex.
The circuit begins with a sensory neuron (receptor) and ends with a motor neuron(effector).
The components of reflex arc- Receptors → Sensory neuron→ Spinal cord→ Motor neuron→ Muscle.
It is a rapid and automatic response to a stimulus.
Essential for producing quick involuntary responses aimed to prevent injury.
Final answer: The correct sequence of components of reflex arc - Receptors → Sensory neuron→ Spinal cord→ Motor neuron→ Muscle
