Question

Argon is the major constituent of inert gases present in air.

• A. True
• B. False

Answer 1

The correct option is A True

Argon is the most abundant and most used of the noble gases. Its chief uses are in metallurgy, where it provides an inert atmosphere in which hot metals can be worked. Because argon is so very unreactive, it prevents chemical reactions of the very hot metal being welded or forged.
