Phagosome with lysosome, is consistent with established principles of cell signaling, receptor pharmacology and cellular regulation. Experimental measurements of binding parameters, genetic loss-of-function studies and pharmacological interventions all converge on the same interpretation. Related options address neighboring concepts but do not satisfy the precise criterion stated in the question.

Opsonization is the coating of a particle with host proteins that facilitate its recognition and uptake by phagocytes. Complement fragments such as C3b and acute-phase proteins such as C-reactive protein function as opsonins. Binding of these molecules to microbial surfaces engages complement receptors or Fc receptors on macrophages and neutrophils, dramatically enhancing phagocytosis.
