Step-by-step explanation:
To achieve the SSI Advanced Open Water Diver rating, a diver must complete the requirements listed in option B: Complete 4 Specialty Courses and log a total of 24 dives. It is important to note that these requirements ensure the diver has a wide range of skills and experiences necessary for advanced open water diving.
While gaining more experience, innovations in diving equipment and processes have also allowed for an increase in productivity and safety for divers, as has been noted with the increased diver carrying capacity from 4 m²/dive to 20 m²/dive for experienced divers. This increase reflects improvements in technology and practices reducing diver exposure to critical situations (CS) and enhancing the overall diving experience.
