Both $(A)$ and $(R)$ are true,and $(R)$ is the correct explanation of $(A)$

(A) As the atomic size of noble gases increases from $He$ to $Xe$,the magnitude of the interatomic van der Waals' forces increases.Stronger van der Waals' forces require more energy to overcome,which leads to an increase in the boiling point of the noble gases from $He$ to $Xe$.Therefore,both $(A)$ and $(R)$ are true,and $(R)$ is the correct explanation of $(A)$.
