विकल्प

• Activation of the complement cascade directly

• Pore formation in the pathogen membrane

• Clumping of antigens together

Answer 1

The primary action of opsonization is to mark the pathogen for phagocytosis. When antibodies coat the surface of an antigen, they serve as signals that enhance recognition and uptake by phagocytic cells.
