Final answer:
The size of the gap needed to safely cross a road depends on how fast or slow traffic is approaching and the type of maneuver you will make.
Step-by-step explanation:
The correct statement is b) The size of the gap needed will depend on how fast or slow traffic is approaching and the type of maneuver you will make.
The size of the gap needed to safely cross a road depends on several factors, including the speed of oncoming vehicles and the type of maneuver you need to make. For example, if you need to make a left turn, you will need a larger gap than if you are making a right turn.
Additionally, the time it takes for a car to stop depends on its speed and the condition of the road. Faster-moving cars require a larger gap to safely cross the road.
