Correct answer: (d) 3, 2, 1
Explanation:
In XeF2 Total number of valence electrons of Xe = 8, two electrons shared with 2F atoms, 6 electrons left hence 3 lone pairs, in XeF4 4 shared with 4F atoms 4 left hence 2 lone pairs; in XeF6 6 shared with 6 F atoms 2 left hence 1 lone pair.

Correct answer: (d) 3, 2, 1
Explanation:
XeF2 has a linear shape. Its hybridization is sp3d which means it should have a trigonal bipyramidal shape. Since it has 3 lone pairs, they occupy the equatorial triangle.
has hybridization. It has a square planar shape and lone pair of electrons.
has one lone pair of electrons. The out of electrons of Xenon are shared by atoms of fluorine.
