The maximum speed at which a car can safely negotiate an unbanked curve depends on the diameter of the curve, acceleration due to gravity, coefficient of static friction between the road and the tires, and the ratio of the static frictional force between the road and the tires and the normal force exerted on the car. The coefficient of kinetic friction between the road and the tires only comes into play if the car starts to skid, which is not a safe way to negotiate a curve. Therefore, D is the correct answer as it is the factor that does not affect the maximum safe speed on an unbanked curve.
