What types of skills and knowledge are important for performing rescues and recoveries?

The choice indicating "All answers are correct" emphasizes the importance of a comprehensive skill set and knowledge base required for effective rescues and recoveries. Each aspect mentioned in the other choices contributes significantly to a diver's ability to perform rescues safely and efficiently.

Full expert training and rigorous practice are fundamental as they equip divers with the advanced techniques and confidence needed to handle emergency situations. This training often includes specific protocols and skills related to distress situations, making it essential for effective rescues.

Knowledge of the dive site is crucial because understanding the environment where rescues may occur allows divers to identify potential hazards, currents, and safe exit points. Familiarity with the dive site can also enhance situational awareness during incidents, improving response times.

Participation in rescue drills is vital because it provides practical experience in a controlled environment, reinforcing the skills learned during training. Regularly engaging in drills helps divers maintain readiness, as well as refine their teamwork and communication skills, which are key during actual rescue scenarios.

By combining expert training, site knowledge, and drill participation, divers can develop a well-rounded and reliable skill set for managing rescue and recovery situations effectively. This holistic approach underscores why "All answers are correct" is the most appropriate choice, as each element plays a critical role
