Solution

The correct option is A True
This iron-dependent enzyme uses iodine ions and hydrogen peroxide to generate iodine, which plays a central role in the production of thyroid hormones. So good levels of both iodine and iron (and selenium) are needed for the body to be able to produce adequate amounts of thyroid hormones. Hence, the correct answer is 'True'.
