The scenario that is BEST suited for a switch case statement is determining the rate for a ferry based on vehicle type.
This is because a switch case is most effective when you have multiple distinct cases to evaluate a variable against, such as different vehicle types (e.g., car, truck, motorcycle, etc.), allowing for clear and organized handling of each case. Other scenarios, like determining if it's raining or not, or choosing a random number, are not as suited to the switch case structure.
