Vedclass · Answer

(B) Goitre is an enlargement of the thyroid gland.Thyroid hormones,specifically $T_3$ (triiodothyronine) and $T_4$ (thyroxine),require iodine for their synthesis.When there is a deficiency of iodine in the diet,the thyroid gland cannot produce sufficient amounts of these hormones.This leads to a decrease in the negative feedback on the pituitary gland,causing it to release more $TSH$ (thyroid-stimulating hormone).Continuous stimulation by $TSH$ causes the thyroid gland to enlarge,a condition known as goitre.
