Reflex Arc
The neural pathway that controls a reflex action, typically comprising a sensory receptor, a neural pathway, and an effector.
Motor Neuron
A type of nerve cell that transmits signals from the brain and spinal cord to muscles, causing them to contract.
Sensory Receptor
A specialized cell or group of nerve endings that responds to sensory stimuli such as light, sound, or touch.

Final Answer :
E
Explanation :
The correct sequence for a reflex arc starting with the sensory receptor is: sensory receptor (5), sensory neuron (4), interneuron (2), motor neuron (1), and finally the effector (3). This pathway correctly describes the flow of information from the point of stimulus to the response.
