Which element is needed for the formation of thyroxine hormone?

Answer and explanation

Correct answer: Iodine

The governing concept is the mineral requirement for thyroid-hormone synthesis. Iodine is incorporated into thyroxine, which is produced by the thyroid gland and helps regulate metabolism. Therefore, option A is correct. If dietary iodine is insufficient, thyroxine production may be disturbed and the thyroid can enlarge, producing goitre. Iron, calcium, and sodium are important nutrients or ions but are not the specific element asked for.
