c) Helium d) None of these

Answer 1

Hello.... First of all G.M

Here is your answer

Deep sea divers are under very high pressure of water, at that pressure oxygen are not able to dissolve in our blood so helium is used to fulfill the requirement.

So the answer would be option a ( mixture of helium with oxygen )
