<h2>Correct answer is option "B"</h2>
Explanation:
- Divergent pathways found in sensory pathways of the CNS.
- Somatic senses are the senses that have to do with touch. Tickling and pain, like on Patrick's legs, are somatic senses, but so are other things that you might not think of right away, like temperature and movement. Somatosensory pathways relay information between the brain and nerve cells in the skin and organs.

- Hence, the correct is option b "divergent"
