To solve this problem, we need to match the interhalogen compounds in Column I with their corresponding geometries in Column II.$\newline$Let's analyze each interhalogen compound:$\newline$• (a) $XX'$: This is a diatomic molecule, and its geometry is linear.$\newline$• (b) $XX'_3$: This compound has a T-shaped geometry.$\newline$• (c) $XX'_5$: This compound has a square pyramidal geometry.$\newline$• (d) $XX'_7$: This compound has a pentagonal bipyramidal geometry.$\newline$Now, let's match these with the options provided:$\newline$Option 1: (a)->(iii), (b)->(i), (c)->(iv), (d)->(ii)$\newline$Option 2: (a)->(v), (b)->(iv), (c)->(iii), (d)->(ii)$\newline$Option 3: (a)->(iii), (b)->(i), (c)->(iv), (d)->(ii)$\newline$Option 4: (a)->(iii), (b)->(iv), (c)->(i), (d)->(ii)$\newline$Analyzing the options:$\newline$• Option 1 matches correctly: (a)->(iii), (b)->(i), (c)->(iv), (d)->(ii).$\newline$Therefore, the correct option is Option 1.
