Final Answer : B, Explanation :  People are rational and will weigh the costs and benefits of using a toll road. If the toll is high enough, some people will choose to use alternative modes of transportation or travel at different times of day to avoid paying the fee. This can lead to a reduction in traffic congestion. Options A, C, and D may have some impact on reducing traffic congestion, but they are unlikely to be as effective as a toll road because they do not create a strong enough incentive for people to change their behavior.
