Final answer:
Graves' disease causes the production of antibodies against TSH, leading to hyperthyroidism with symptoms such as heat intolerance and an irregular heartbeat. The correct option is b.
Step-by-step explanation:
The condition in which antibodies are produced against thyroid-stimulating hormone (TSH) is called Graves' disease.
This autoimmune disorder is characterized by the production of thyroid-stimulating immunoglobulin (TSI), which acts similarly to TSH, causing hyperthyroidism.
TSI targets and binds to the TSH receptors on the thyroid gland and can either stimulate excessive thyroid hormone production or block it, leading to a range of symptoms including heat intolerance, rapid and irregular heartbeat, weight loss, goiter, and Graves ophthalmopathy. The correct option is b.
