In deep-sea diving, divers use a mixture of gases consisting of oxygen and

A Hydrogen
B Nitrogen
C Argon
D Helium

Correct Answer: Nitrogen

Air is not the "ideal" breathing mixture for diving as with a concentration of approximately 79 percent nitrogen, compressed air poses two potential problems for all divers: susceptibility to nitrogen narcosis and at deeper depths; and decompression sickness. So divers use Nitrox, a gaseous mixture of nitrogen and oxygen. It is also known as ‘Enriched Air.’
