(B) The number of lone pairs on the central $Xe$ atom can be calculated using the formula: $	ext{Lone pairs} = \frac{1}{2} (V - M)$,where $V$ is the number of valence electrons of the central atom and $M$ is the number of monovalent atoms attached.For $XeF_2$: $V = 8$,$M = 2$. $	ext{Lone pairs} = \frac{1}{2} (8 - 2) = 3$.For $XeF_4$: $V = 8$,$M = 4$. $	ext{Lone pairs} = \frac{1}{2} (8 - 4) = 2$.For $XeF_6$: $V = 8$,$M = 6$. $	ext{Lone pairs} = \frac{1}{2} (8 - 6) = 1$.Thus,the number of lone pairs is $3, 2, 1$.
