Iodized salt is used to prevent a human condition known as

• A. Scurvy
• B. Anemia
• C. Goiter
• D. Rickets

Answer: (C)

Iodine is needed to make thyroid hormones. When the body doesn’t get enough iodine, the thyroid gland increases its activity and often enlarges, causing a goiter. Adding iodine to salt provides a reliable source of this nutrient, helping maintain normal thyroid function and preventing the gland from swelling.

Other conditions listed come from different nutrient deficiencies: scurvy is due to lack of vitamin C, anemia is commonly from insufficient iron or other factors, and rickets arises from vitamin D deficiency.
