Solution
The correct option is C Adrenal medulla
The adrenal medullary cells are modified postganglionic neurons, and preganglionic autonomic nerve fibres lead to them directly from the central nervous system. It is the innermost part of the adrenal gland, consisting of cells that secrete epinephrine (adrenaline) and norepinephrine (noradrenaline). It is not under direct control of the pituitary gland.
So, the correct answer is option B.
