Which diver certification agencies offer Nitrox certification?

The correct choice indicates that PADI, NAUI, and SSI are widely recognized diving certification agencies that offer Nitrox certification courses. Each of these organizations has developed comprehensive training programs specifically for the use of enriched air Nitrox.

PADI (Professional Association of Diving Instructors) is one of the largest diver training agencies globally and provides a popular Enriched Air Diver course, which teaches divers how to safely use Nitrox for recreational diving. Similarly, NAUI (National Association of Underwater Instructors) provides courses that cover the principles and practices of using Nitrox, emphasizing safety and dive planning.

The inclusion of these three agencies highlights the widespread availability and recognition of Nitrox certification in the recreational diving community, making it accessible to divers across different regions.
