Which halogen is added to salt to aid thyroid function?

Explanation:
Iodine is essential for making thyroid hormones, which regulate metabolism and development. The thyroid needs iodine to form hormones like T3 and T4. Since the body cannot produce iodine, it must come from the diet, and iodized salt is a common way to ensure people get enough. The other halogens—fluorine, chlorine, and bromine—don’t participate in thyroid hormone production in humans, and they aren’t added to salt for thyroid function. That makes iodine in salt the correct choice because it directly supports the thyroid’s ability to function properly.
