Hint: Noble gas are elements that are positioned in the periodic table's 18th group. They are also named inter gases. Some examples like helium, argon, neon, xenon, Krypton, etc. are noble gases.
Complete Step by Step Solution:
Noble gases are also known as the name of inert gases due to their non-reactive nature. They are non-reactive because of completely filled the outermost shell.
Let's understand all the options one by one. The element argon is a noble gas. So, its compounds are rarely found. There, option A is not true.
The compounds of helium are also not found because of the inert nature of the helium. Therefore, option C is also wrong.
The compound neon is also a noble gas whose nature is inert. Therefore, option D is also wrong.
Let's discuss the compounds of xenon. The size of the xenon atom is large. And, due to the large size, there is a weak attraction of the electrons to the nucleus. Therefore, xenon undergoes reactions with elements such as oxygen and fluorine which are highly electronegative and small in size. So, the valence electron of the element xenon is attracted by oxygen and fluorine. And this results in the compound formation of xenon. Some of the compounds formed by xenon are \[{\rm{Xe}}{{\rm{F}}_{\rm{2}}}{\rm{,XeO}}{{\rm{F}}_{\rm{2}}}{\rm{,Xe}}{{\rm{F}}_{\rm{4}}}{\rm{,XeO}}{{\rm{F}}_{\rm{4}}}{\rm{,Xe}}{{\rm{F}}_{\rm{6}}}{\rm{,Xe}}{{\rm{O}}_{\rm{3}}}\] .
Hence, option C is right.
Note: It is to be noted that inert gases exist independently in the form of the monatomic molecules. For example, helium molecules exist as He, neon molecules as Ne, etc. The noble gas, radon, is radioactive in nature.
