Question

a addisons disease.
b adrenal feminization.
c cushings syndrome.
d pheochromocytoma.

Explanation:

Gynecomastia is the enlargement of male breast tissue. Addison's disease is characterized by adrenal insufficiency and does not typically cause gynecomastia. Adrenal feminization is a rare condition where the adrenal glands produce excessive amounts of estrogen - like hormones, which can lead to gynecomastia in males. Cushing's syndrome is due to excessive cortisol and presents with symptoms like central obesity, moon face etc., not gynecomastia. Pheochromocytoma is a tumor of the adrenal medulla that secretes excessive amounts of catecholamines (e.g., epinephrine, norepinephrine) and causes symptoms like hypertension, palpitations etc., not gynecomastia.
