Reflex Arc
The neural pathway that mediates a reflex action, involving sensory receptors, nerves, and the spinal cord.
Integration Center
An area of the central nervous system, such as the brain or spinal cord, where information is processed and interpreted.
Sensory Neuron
A type of neuron that transmits signals from sensory receptors towards the central nervous system.

Final Answer :
B
Explanation :
The correct order of components in a reflex arc is receptor, sensory neuron, integration center, motor neuron, and effector. The receptor picks up the stimulus, the sensory neuron transmits it to the integration center, the integration center processes the information and sends a response to the motor neuron, which then activates the effector to carry out the appropriate response. Choice B represents this correct order.
