Rationale:A) Placing the child in a forward-facing car seat before the appropriate age and size increases the risk of injury.B) Placing the child in the front seat, even in a rear-facing car seat, is not recommended due to the risk of airbag deployment.C) Booster seats are used for older children who have outgrown their forward-facing car seats, but are not yet big enough to use the seat belt properly. Booster seats should be used until the child is at least 4 feet 9 inches tall and between 8 and 12 years old.D) Placing the child in a rear-facing car seat until age 2 is recommended by safety guidelines to provide optimal protection for the child's head, neck, and spine.
