What is the minimum number of officers required for carries during a rescue?

The correct choice is based on the principle of safe and effective rescue operations. When carrying an individual during a rescue, having two officers ensures that the weight is distributed evenly and allows for better stability and control. This allows each officer to handle a portion of the load, reducing the risk of injury to both the rescuers and the individual being rescued.

Additionally, having two officers provides an opportunity for coordination and communication, which is critical in emergency situations. They can strategize their movements, manage obstacles more effectively, and respond to any sudden changes in the situation that may arise. This level of teamwork increases the overall efficiency of the rescue operation and enhances safety for everyone involved.

In contrast, having only one officer would likely lead to difficulties in managing the individual being rescued, which could result in further complications or hazards. More officers than necessary also does not improve the immediate capacity needed for the task, so two is the optimal number.
