Solution

The correct option is A Deficiency of iodine in diet
Cretinism is a condition of severely stunted physical and mental growth owing to untreated congenital deficiency of thyroid hormone (congenital hypothyroidism) usually owing to maternal hypothyroidism. Cretinism is therefore most probably due to a diet deficient in iodine.
