Sensory receptors detect external stimuli. The receptors respond to the stimuli outside the body, such as sight, smell, taste, and temperature. The receptors are under the control of the central nervous system.

The hair cells look like test tubes, and they receive information from the brain. It also works as chemical messenger. The total effect of their mechanical action is to change the mechanical properties of the basilar membrane at specific spots.

Thus, hair cell-mechanoreceptors are paired categories.

Therefore the given option is incorrect.

Snakepit organ present in the snake eye. The sensory organ thermoreceptor will respond to external stimuli. The snakes are highly sensitive to thermoreceptors. They maintain the body temperature according to the surrounding environment.

Thus, snakepit organ-thermoreceptors are paired category.

Therefore the given option is incorrect.

The chemoreceptors are neurotransmitters, and they send a chemical signal to the nerves. The chemoreceptors are present in test buds. The molecules present in food interact with saliva bound to taste receptors. The taste is often referred to as chemical senses.

Thus, taste receptors-chemoreceptors are paired categories.

Therefore the given option is incorrect.

Electromagnetic receptors help in determining the light intensity, the receptors present in the eye, but olfactory receptors help in smell are present in the nasal chamber of the nose. So the olfactory receptors are not paired with electromagnetic receptors.

Thus, olfactory receptors-electromagnetic receptors are not paired categories.

Therefore the given option is correct.
