During an Infection, White Blood Cells Travel to the Infected

During an infection, white blood cells travel to the infected site and phagocytize the pathogens.After phagocytosis, primary lysosomes fuse with the phagocytic vesicle to form a larger vesicle called a secondary lysosome.The reason for this is:

A) to introduce antibodies to the phagocytic vesicles.
B) to wrap the pathogen in additional membrane, rendering them harmless.
C) to coat the bacteria in lipids derived from the Golgi complex, which cover and smother them.
D) to mix the pathogens with strong hydrolytic enzymes and destroy them.
E) to prepare the bacteria for export from the body.
