The correct reflex order is a stimulus activates a receptor and than impulse travels through sensory neuron to the CNS.
The reflex arc is composed of sensor, sensory neuron, control middle, motor neuron, and muscle. these elements paintings as a relay group to take facts up from the sensor to the spinal twine or mind and go into reverse to the muscle tissues
A reflex movement frequently entails a totally simple fearful pathway referred to as a reflex arc. A reflex arc starts with receptors being excited. They then send indicators alongside a sensory neuron to your spinal cord, where the signals are exceeded directly to a motor neuron.
A reflex action is a way for the body to automatically and hastily reply to a stimulus to any further damage to the frame. It follows this widespread series and does no longer involve the brain: stimulus → receptor → sensory neurone → relay neurone → motor neurone → effector → response.

The correct order of reflex is b) and then a) i.e. impulse travels through sensory neuron to the CNS and a stimulus activates a receptor.
In a reflex, a stimulus activates a receptor and the information travels through a sensory neuron to the Central Nervous System (CNS).
A receptor is a cell that responds to a stimulus like light, heat or pain.
An impulse is the signal that travels through the neurons from affector to effector.
The information is carried out through a sensory neuron which connects the receptor and the CNS.
CNS comprehends the information and send the signals to the effector through the Motor Neuron.
Motor neuron is a neuron that carries information from CNS to the Effector cells, i.e. which responds to the stimulus.
The motor neuron transmits information to the effector cells and hence the reflex arc is completed after the response.
