• Matching Vascular and Cellular Terminology in Inflammation:
• Margination $\longrightarrow$ (III) Alignment of leukocytes along vascular endothelial surfaces: During acute inflammation, slowing of blood flow (stasis) allows white blood cells to move from the central axial stream toward the periphery of the vessel lumen.
• Diapedesis (Transmigration) $\longrightarrow$ (I) Emigration of leukocytes across the capillary basement membrane: Active squeezing of leukocytes through endothelial intercellular junctions into perivascular tissues.
• Chemotaxis $\longrightarrow$ (IV) Directional migration along a chemical concentration gradient: Leukocyte locomotion guided by chemoattractants (C5a, leukotriene $B_4$, bacterial formyl peptides).
• Opsonization $\longrightarrow$ (II) Coating of microbes to facilitate phagocytic recognition: Coating antigens with antibodies (IgG) or complement fragments (C3b, iC3b) recognized by phagocyte Fc and CR1 receptors.
• Conclusion: (A) - (III), (B) - (I), (C) - (IV), (D) - (II) (Option 3).

Correct option: (3) (A) - (III), (B) - (), (C) - (IV), (B) - (I)
