A severe iodine deficiency during fetal development can lead to which condition?

Explanation:
Iodine is essential for making thyroid hormones, which are crucial for brain development and overall growth in the fetus. When iodine intake is severely deficient during pregnancy, the fetus can’t produce enough thyroid hormone, leading to congenital hypothyroidism with severe intellectual disability and growth retardation known as cretinism. The other conditions listed—anemia, osteoporosis, and hyperglycemia—stem from different causes (iron or B12 deficiency, calcium/vitamin D issues, and problems with glucose regulation, respectively) and are not linked to fetal iodine deficiency.
