As we learnt in 

Structure of Xenon tetrafluoride -

Square planar and hybridisation is Sp3d2

- wherein

 

 (lone pair electron = 2) XeF4 is square planar with sp3d2 hybridization.

(lone pair electron=0) CF4 is tetrahedral with sp3 hybridization.

(lone pair electron =1) SF4 is trigonal bipyramidal with sp3d hybridization.


Option 1)

the same with 2, 0 and 1 lone pairs of electrons on the central atom respectively.

This option is incorrect.

Option 2)

the same with 1, 1 and 1 lone pair of electrons on the central atoms respectively.

This option is incorrect.

Option 3)

different with 0, 1 and 2 lone pairs of electrons on the central atom respectively.

This option is incorrect.

Option 4)

different with 1, 0 and 2 lone pairs of electrons on the central atom respectively.

This option is correct.
