In deep-sea diving, divers use a mixture of gases consisting of oxygen and
A. Hydrogen
B. Nitrogen
C. Argon
D. Helium
Answer: Option D
Solution (By Examveda Team)
Question: Deep-sea divers breathe a special mix of gases to stay safe underwater. Oxygen is part of the mix, but what other gas is commonly added?Explanation: Divers need to breathe underwater, just like we do on land. Oxygen is essential for life, but breathing pure oxygen at high pressure (like deep underwater) can be dangerous.
That's why another gas is added to dilute the oxygen. Helium is the most common choice because it is:
1. Lightweight: This makes it easier to breathe at depth.
2. Inert: It doesn't react with the body or other gases.
3. Safe at high pressure: Unlike some other gases, helium doesn't cause problems when breathed under pressure at great depths.
Therefore, the correct answer is D: Helium.

Oxygen and helium gases mixture uses which called heliox. Divers use it to avoid narcosis. Becaouse helium does not dissolve with blood where nitrogen quickly dissolve with blood.
Helium is correct
Oxygen and helium used in deep sea diver because helium is not mixed with blood and also helium is low weight. Right answer is Helium.
Its oxygen and helium which is used in deep sea divers
