For children, what is the general recommendation regarding the minimum height or age before they can safely stop using a booster seat and use an adult seat belt alone?

✓ Correct Answer: Option B

Most safety guidelines recommend that children remain in a booster seat until they are at least 4 feet 9 inches (145 cm) tall, which usually occurs between 8 and 12 years of age, ensuring the adult seat belt fits properly across their shoulder and hips.
