The correct answer is:
B. Diapedesis
Diapedesis is the process by which white blood cells (leukocytes) move through the endothelial lining of blood vessels to enter the surrounding tissue. It is not a direct event of phagocytosis. The other options (Ingestion, Phagolysosome formation, Destruction, and Chemotaxis) are all events associated with phagocytosis.
