How many rescuers can the boat accommodate according to capacity?

The answer indicates that the boat can comfortably carry 4 rescuers along with an additional 3 others. This reflects an important aspect of boat safety and operational efficiency, ensuring that there are enough trained personnel on board to manage emergencies effectively while also allowing for the safe transport of additional individuals who may require assistance.

In rescue operations, the capacity limit is crucial. Having a sufficient number of rescuers ensures that there are enough trained individuals to perform essential tasks such as providing first aid, steering the boat, and managing safety protocols. The other choices either do not provide enough rescuers to meet potential demands of a rescue scenario or allocate too few spaces for additional non-rescuers, which could hinder the boat's function in emergencies.

Choosing 4 rescuers and 3 others strikes a balance between having high-quality support personnel and maximizing the overall capacity of the boat for effective rescue operations.
