A nurse is teaching the parent of a school-age child about bicycle safety. Which of the following instructions should the nurse include in the teaching?

A. The seat height should allow the child to have both feet flat on the ground when seated, ensuring they can stop the bike safely. B. Walking the bicycle through intersections is the safest practice, as it ensures the child is aware of their surroundings and less likely to be involved in a collision. C. Children should ride with the flow of traffic to be visible to drivers, not against it. D. Keeping the bike 3 feet from the curb is not ideal. Children should ride as close to the curb as possible without endangering themselves.
