The correct answer is: It involves the uptake of cellular debris in large endocytic vesicles.
The immune cells like macrophages have the ability to "eat" or "devour" pathogenic cells by ingesting them. This process of cell-eating is called phagocytosis. Phagocytosis can be defined as a process to ingest of engulf other cells or particles. The ingested particle is surrounded by a vesicle called endocytic vesicles that help in digestion.
