Answer 1

Answer:

The correct answer will be option-B

Explanation:

Locus coeruleus is a nucleus composed of neurons in the pons region of the brainstem. The pons and brainstem are involved in the physiological responses of panic and the stress conditions.

Nor-epinephrine is the hormone which is produced in the stress and fear conditions and produces fight or flight response. The nor-epinephrine is produced from the adrenal medulla in the kidney and the brain. The part of the brain involved in the production of Nor-epinephrine is locus coeruleus.

Thus, Option-B is the correct answer.
