If b is the wheel track of a vehicle and h is the height of centre of gravity above road surface, then to avoid overturning and lateral skidding on a horizontal curve, the centrifugal ratio should always be

• A. less than b/2h and greater than co-efficient of lateral friction
• B. less than b/2h and also less than co-efficient of lateral friction
• C. greater than b/2h and less than co-efficient of lateral friction
• D. greater than b/2h and also greater than coefficient of lateral friction
