Argument: To reduce traffic congestion, city officials propose increasing the tolls on bridges and tunnels during peak hours. They argue this will encourage commuters to use public transportation instead, thereby easing traffic flow. The city officials' argument relies on which of the following assumptions?
✓ Correct Answer: Option B
For commuters to shift to public transportation, it must be a practical option. If public transport isn't available or convenient, raising tolls won't reduce congestion as commuters will simply pay more or find other routes, rather than switching.
