Which of the following disorders is caused by the oversecretion of a hormone?

Exophthalmic goitre, also known as Graves' disease is caused by the oversecretion of thyroid hormones. This condition occurs when the thyroid gland produces an excessive amount of thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3). This can lead to a variety of symptoms, including enlargement of the thyroid gland (goitre), weight loss, rapid heartbeat, nervousness, sweating, tremors, and protrusion of the eyeballs (exophthalmos).
