D. The receptor potential is carried by neuroglia.

Explanation:

A receptor potential is a trans-membrane potential difference (i. e the difference in electric potential between the interior and exterior of a biological cell) produced by activation of a sensory receptor. Hence, they can be triggered by an action potential.

These receptors potential are activated by a signal transduction indicating that they can respond to stimuli and convert one sensory stimuli from one form to another.

Odorous molecules which are present along the olfactory nerve's axons act as stimuli (chemical stimuli) which in turns bind to receptor proteins extending from cilia, initiating electric signals that travel along its location to the brain.

Receptor potentials arenot carried by neuroglia because neuroglia are cells in your nervous system that are not neurons. Their role is to be the support team and cheerleaders for the neurons.
