Which of the following are NAUI-sanctioned specialty courses?

• A. All of the Above
• B. Underwater Digital Imaging
• C. Night Diver
• D. Underwater Naturalist

Answer: (A)

NAUI offers a variety of sanctioned specialty courses, and the three listed options each belong to that official set. Underwater Digital Imaging covers underwater photography and imaging skills, Night Diver focuses on planning and conducting dives after dark with proper lighting and safety, and Underwater Naturalist emphasizes observing, identifying, and understanding marine life and habitats. Since all three are recognized NAUI specialties, the choice that includes all of them is correct. If you picked just one, you’d miss the other valid specialties, demonstrating why “All of the Above” is the best answer.
