Answer:b) Steering the vehicle
Explanation: If a tire fails or blowout the best option is for the driver to focus on steering the vehicle until he steers it a safe place by the side of the road, This is because if a tire fails or blowout it causes the vehicle to move towards the direction of the failed tire. After having a proper control on the steering, it is advised that the driver continue to reduce the acceleration of the vehicle till it is finally stopped in a safe place before carrying out other activities.
