Thyroxine hormone is secreted by which gland?
Answer and explanation
Correct answer: Thyroid gland
Thyroxine is the principal hormone secreted by the thyroid gland in the neck. It helps regulate metabolism, growth, and development, and its production requires iodine. Therefore option A is correct. The pancreas secretes insulin and glucagon, the adrenal gland secretes adrenaline and other hormones, and the salivary gland produces saliva rather than thyroxine. These differences identify the thyroid as the correct gland.
