ANSWER · D
Rain makes the road slippery, lowering the sliding friction coefficient between the tire and the road, which reduces friction. So when emergency braking, the tires stop rolling and slide forward; sliding friction cannot effectively slow the car, causing it to slide forward a long distance. After rain, slippery roads easily cause accidents under hard braking.
