ICl is a diatomic interhalogen, hence linear — (A)–(IV).
$Cl{F}_3$ has $A{X}_3{E}_2$ geometry (trigonal-bipyramidal electron arrangement with two lone pairs on Cl), giving a T-shape — (B)–(I).
$I{F}_5$ has $A{X}_5{E}_1$ geometry (octahedral electron arrangement, one lone pair on I), giving a square pyramid — (C)–(II).
$I{F}_7$ has $A{X}_7$ geometry with no lone pairs — pentagonal bipyramidal — (D)–(III).
Hence A–IV, B–I, C–II, D–III.
