What must vehicle B do in relation to vehicle A in a specified situation?

In the context of road rules and safe driving practices, the correct response involves understanding various driving maneuvers and their implications depending on specific traffic situations. When multiple choices can be correct, particularly in scenarios involving rules of the road, it's important to recognize why they are collectively valid.

When considering the actions of vehicle B in relation to vehicle A, all of the listed actions can be seen as appropriate responses. For instance, if vehicle A is stationary at a stop line, vehicle B should indeed stop immediately behind the stop line, ensuring adherence to traffic regulations and maintaining safety.

Should vehicle A start moving, vehicle B may need to drive nearer, ensuring that it maintains safe following distances and is prepared to continue in the flow of traffic. If vehicle A is traveling slowly or has created a situation conducive for overtaking, then vehicle B can, if legally and safely possible, overtake vehicle A.

It's essential to approach driving with the understanding that situational awareness dictates the right course of action. Therefore, vehicle B must be capable of taking any of these actions based on the behavior and position of vehicle A, which supports the selection of the option indicating that vehicle B has multiple appropriate actions to consider in relation to vehicle A.
