This allows for a more intuitive and responsive steering experience, as your body movements directly influence the direction of the vehicle.

Correct Answer B. It has three wheels
Explanation The Trikke Scooter is stable because it has three wheels. Having three wheels provides a wider base of support, which increases stability and balance. With an additional wheel, the scooter is less likely to tip over, especially during turns or when maneuvering on uneven surfaces. The three-wheel design allows for better weight distribution, making it easier for the rider to maintain control and stability while riding.
