Which vehicle is specifically permitted to tow the boat and trailer?

The correct answer highlights the specific types of vehicles that are permitted to tow a boat and trailer based on their design and capabilities. In this context, the vehicle most suitable for towing is generally a car or a truck that is equipped for such tasks.

Cars often possess the necessary towing capacity, which is essential for safely transporting boats. They are designed with features like a hitch and adequate power to manage the weight of the trailer and the boat it carries.

While pumper and aerial vehicles are instrumental for firefighting and emergency operations, they are not typically designed for towing boats due to their size, weight, and orientation towards carrying firefighting equipment rather than towing capacities. Therefore, they may not meet the safe towing requirements or have the necessary towing apparatus.

In summary, the focus on the car indicates it is the vehicle best suited for towing duties in this context, making it the correct choice.
