Verified by Experts

The correct Answer is:
B
Phenylalanine-N-Methyl Transferase (PNMT) is enzyme found in the adrenal medulla that converts an norepinephrine (noradrenaline) to epinephrine (adrenaline). PNMT catalyses the transfer of a methyl group from SAM (S-adenosyl-L-methionine) which is a factor to norepinephrine, converting it into epinephrine.
