D. all of these

Answer

Explanation

Both the terms 'the insert gases' and 'the rare gases' are misnomers .because the discovery of `Xe` fluorides in. `1962` shows that they are not really inert but can react with a few elements under suitable conditions ,and `Ar` makes up about `0.9%` by volume of the atmosphere,
The name 'noble gases' implies that they react only under suitable conditions and form very few compounds.
