Why can iodine deficiency increase the chance of enlargement of the thyroid gland?

Answer and explanation

Correct answer: Because iodine is necessary for thyroxine production

The governing concept is thyroid hormone production and feedback regulation. Iodine is a necessary raw material for making thyroxine in the thyroid gland. When iodine is deficient, thyroxine production falls; the body may stimulate the thyroid more strongly, causing enlargement of the gland, known as goitre. Therefore option A is correct. The other choices incorrectly connect iodine with insulin transport, reflex arcs, or neuron structure.
