The correct answer indicates that a child should use a rear-facing car seat until they are at least under 2 years old. This recommendation is based on safety guidelines established by various authorities, including the American Academy of Pediatrics. Research shows that infants and toddlers are significantly more protected in a rear-facing car seat, as it better supports their developing bodies in the event of a crash.

Rear-facing seats are designed to absorb the force of a collision more effectively, distributing impact forces along the back of the seat, thus reducing the risk of severe injury to a child's head, neck, and spine. Until the age of 2, children's bodies are still growing and maturing, making this age threshold crucial for their safety.

The other age options provided are either too young or too old, which do not align with established safety guidelines. While it is advised that children remain in a rear-facing seat as long as possible, up to the limits of the car seat's weight and height requirements, the specific age threshold of under 2 years is a widely accepted standard for transitioning from rear-facing to forward-facing seats.
