A is wrong because you cannot TALK a vehicle into the city. Just kiding.
B is right because it removes the financial cause as the reason to DETER people from driving the private vehicle into the city since these drivers are paying a lot of EXTRA money for parking. They will not give it a damn if they have to pay five more dollars.
