ANS: A
Graves disease results from a form of type II hypersensitivity in which there is stimulation of the thyroid by autoantibodies directed against the TSH receptor. The thyroid-stimulating antibodies stimulate TSH receptors; it is not an ectopic secretion. Graves disease is manifested by elevated levels of thyroid hormones. Iodine deficiency leads to goiter but not Graves disease.
