To prepare $XeF_6$,$Xe$ and $F_2$ are mixed at $573 \ K$ and $60-70 \ bar$ in the ratio of

Given below are two statements:
Statement-$I$: Noble gases have very high boiling points.
Statement-$II$: Noble gases are monoatomic gases. They are held together by strong dispersion forces. Because of this,they are liquefied at very low temperatures. Hence,they have very high boiling points.
In the light of the above statements,choose the correct answer from the options given below:

Which of the following pairs of inert gases is used in flash bulbs?

Which one of the following noble gases is the least polarizable?

Which of the following statements are correct regarding $XeF_2$ and $XeF_4$?

Assertion $(A)$: The boiling points of noble gases increase from $He$ to $Xe$.
Reason $(R)$: The interatomic van der Waals' attractive forces increase from $He$ to $Xe$.
The correct answer is:
