The correct answer is option 2: Due to their chemical inertness.

Noble gases are called so because they are chemically inert or unreactive. This means that they do not easily react with other elements or compounds to form new substances. Noble gases have a full complement of electrons in their outermost energy level, making them stable and less likely to gain or lose electrons in chemical reactions.

Option 1 is incorrect because noble gases do not react quickly with other compounds. In fact, they are known for their lack of reactivity.

Option 3 is incorrect because noble gases can react with other compounds, not just carbon compounds.

Option 4 is incorrect because noble gases cannot produce oxygen. Oxygen is a separate element on the periodic table and noble gases do not have the ability to produce it.

In summary, noble gases are called so because of their chemical inertness, meaning they have a low tendency to react with other elements or compounds.
