Answer:
c. within the same dermatome.
Explanation:
Referred pain is pain experienced on a surface area distant from the stimulated organ. Often, the area where the pain is manifested and the related visceral organ has the same spinal cord innervation, which suggests an explanation for this phenomenon.
With the referred pain it is possible for an internal organ to suffer some kind of irritation and this pain is not felt in this organ itself, but in a somatic structure distant from it (somatic pain). When this happens the pain is felt within the same dermatome, which is a skin area with stimuli provided by the cutaneous branches of a single spinal nerve.
