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.
