Answer:

<em>The correct option is D) glial cell</em>

Explanation:

The function of the glial cells is to cover the neurons and to provide insulation between them. They also supply the neurons with oxygen and nutrients. The glial cells are also involved in protecting the neurons from pathogens and removing the dead neurons. Hence, glial cells perform functions other than producing actions when a stimuli is detected.

Other options like option B, sensory neurons, helps to convert external stimuli into electrical impulses.
