Right answer and explanation
Right answer: A. Because the tyres share their grip between braking and steering
A tyre has a limited amount of grip, and the same grip has to serve both braking and holding the car through the bend. Use a lot of it on braking and too little is left for steering, so the car runs straight on or loses the back end. That is why the speed belongs before the bend, not inside it.
