Detailed Solution

The given statement is true.
Concept- Combustible compounds are those that burn to release heat and light in the presence of air. Nothing burns in oxygen. It is an oxidant even if it is not flammable. It is harmful to utilise oxygen around a burning object since it will make the fire burn more quickly and oxygen needs a fire to function.
Thus, oxygen can be referred to as a non-combustible gas. It merely helps the combustion process. As a non-combustible gas, oxygen has a variety of applications,
In gas welding, gas cutting, oxygen scarfing, flame cleaning, flame hardening, and flame straightening, oxygen is combined with fuel gases.
The usage of oxygen is also found in metallurgy. For instance, steel is made with the help of oxygen. By converting carbon into carbon dioxide in a blast furnace, iron oxides are reduced to pure iron. Hence, the statement is true.
Hence, the correct answer is option 1.
