Correct Answer is B

Explanation

A. Incorrect: GERD is common in infants but is not specifically associated with race.

B. Correct: African-American infants are at a higher risk for iron deficiency anemia, particularly if they are born prematurely or have low birth weight. Lower iron stores at birth and dietary differences contribute to this risk.
