Can leaves lying on a roadway have an impact on the braking distance of a vehicle?
aYes, because they may reduce the braking distance.
bYes, because they may extend the braking distance.
cThey do not have an impact on the braking distance.
Why?
The leaves visible on the road can reduce tyre grip, especially when wet. This can increase braking distance and therefore the total stopping distance. That makes B correct, while the answers claiming a shorter braking distance or no effect are incorrect.
