Final Answer :
B
Explanation :
Teratogens are chemicals or other agents that can cause birth defects or malformations in a developing fetus. Iodized sodium chloride is simply table salt with added iodine and is not known to cause birth defects. Carcinogens are chemicals that can cause cancer, not birth defects. Glycogens are actually a type of carbohydrate stored in the liver and muscles, not a chemical that would be associated with birth defects.
