I think that when oxygen and acetylene are proper to welding than why to add extra argon gas, it's costly.

No, the Correct answer is "c".

But on the other hand, argon welding is contain argon gas.

A weld is done so it stays welded and intact without undergoing oxidation, leading to failure. Therefore a protective coating of inert gas (which is usually CO2 or Argon) is used, INEVITABLY, or else the welding is either underwater or in a vacuum. Hence, I Believe [C] should be the right answer.

It is also known as oxy acetylene flame it is of temp of 3700 degree celcius.

Because oxygen react with acetyle and form oxyacetylence gas which help in welding and also form different type of flames which is at very high temperature.

According to me,
Argon is inert gas therefore if the O and acetylene will react then it will more producing temperature. Hence, the answer would D.
