B. Skid marks
Explicación
## Step 1The question is asking us to identify which of the given options can help us determine the speed of a car when it hit the brakes. The options are yaw marks, skid marks, and tire scrub.## Step 2Skid marks are the most relevant option among the given choices. When a car hits the brakes, the wheels lock up and the car begins to skid. The length of the skid marks can provide an estimate of the car's speed before the brakes were applied. This is because the distance a car travels while skidding is proportional to its speed. The faster the car was moving, the longer the skid marks will be.## Step 3Yaw marks and tire scrub are not as directly related to the speed of the car. Yaw marks are the result of the car's wheels being turned while the car is sliding, which can be caused by a variety of factors, not just braking. Tire scrub is the wear and tear on the tires caused by sliding, which can be caused by a variety of factors, not just braking.
