What is the relation between thyroxine deficiency and iodine deficiency?
Answer and explanation
Correct answer: Iodine is necessary for making thyroxine
The governing concept is the role of iodine in thyroid hormone synthesis. The thyroid gland requires iodine to produce thyroxine, a hormone involved in regulating metabolism and development. When iodine intake is insufficient, thyroxine production may fall, and prolonged deficiency can contribute to enlargement of the thyroid gland called goitre. Therefore option A is correct; the other options describe no valid physiological relationship.
