Final answer:
At a T-intersection, vehicles must yield according to traffic signs and rules of the road, not vehicle color.
This correct answer is none of the above.
Step-by-step explanation:
In the context of a T-intersection, the vehicle that must yield is not determined by color but by the traffic signs present and the rules of the road.
Typically, vehicles on the terminating road of a T-intersection must yield to vehicles on the through road. This is usually indicated by a yield sign or a stop sign on the terminating road.
Factors that might influence whether a vehicle must yield could include the presence of a traffic signal, the actions of other vehicles, and right-of-way rules.
This correct answer is none of the above.
