D
Correct answer
Explanation
Iodine deficiency causes goiter, the abnormal enlargement of the thyroid gland as it grows trying to capture more iodine from the blood to produce thyroid hormones. Beri-beri is caused by thiamine (vitamin B1) deficiency. Cataracts are caused by various factors including aging and diabetes, not iodine deficiency. Hernia is a physical defect in muscle tissue, unrelated to nutrition.
