Correct Answer: C

Rationale: The correct answer is C. For infants younger than 1 year, the American Academy of Pediatrics recommends the use of breast milk or iron-fortified formula. If breastfeeding is discontinued before 1 year, it is important to switch to a commercial iron-fortified formula to ensure the infant is receiving all the necessary nutrients for growth and development.
