Correct answer: Thyroid gland and iodine
The governing concept is the dependence of thyroid hormone synthesis on iodine. The thyroid gland produces thyroxine, and iodine is an essential raw material in that hormone’s structure. Inadequate iodine can reduce thyroxine production and may lead to enlargement of the thyroid, called goitre, along with other effects of deficiency. Hence A is the correct pair. The pancreas is associated with insulin, the adrenal gland with adrenal hormones, and bile is linked to the liver.
