If a person has iodine deficiency in food for a long time, which gland will be most affected?
Answer and explanation
Correct answer: Thyroid gland
The governing concept is the role of iodine in thyroid hormone production. The thyroid gland uses iodine to synthesize thyroxine, which helps regulate metabolism, growth, and development. Long-term dietary deficiency can reduce thyroxine production and may lead to thyroid enlargement or goitre. Therefore option B is correct. The pancreas, adrenal glands, and testes have important endocrine functions but do not require iodine as the defining raw material for their principal hormones.
