ALSO, HYDROGEN gas is used in atomic hydrogen welding for shielding the weld zone. Hence protecting the welded part from oxidation or contamination.
H2, C2H2+O2, ARGON (MIG WELDING).
Best resembling option will be option C.

But in heavy fabrication units co2 and argon mixture is also use for MS welding. And for SS welding pure ARGON gas is use.

Bcoz, acetylene burns in oxygen gas producing oxy-acetylene flame which has temp above 3000 degrees. So it is used for welding.

oxygen react with acetylene form oxy acetylene which produces a very high temperature
