Step 1 — Count lone pairs on central atom:

A. : I has 7 bonds + 0 lone pairs → Zero lone pairs → IV

B. : I has 4 bonds + 2 lone pairs → Two lone pairs → III

C. : Xe has 6 bonds + 1 lone pair → One lone pair → II

D. : Xe has 2 bonds + 3 lone pairs → Three lone pairs → I

Step 2 — Matching: A-IV, B-III, C-II, D-I
