Macrophages are phagocytic cells which are involved in endocytosis. It is a process of engulfing antigen. Endocytosis occurs when a cell destroys something such as a virus or an infected cell.
The correct steps of endocytosis in chronological order as follows:
6. Cell recognizes the viral particle as foreign material.
1. Cell surface receptors bind to the viral particle.
4. Cell membrane curves around toward the cell's interior.
3. Viral particle is surrounded by the cell membrane.
2. Lysosome within the cell encloses the viral particle.
5. Lysosome's digestive enzymes destroy the viral particle.

Answer:
Commensalism
Explanation:
Personally I would choose commensalism, in commensalism I would be benefiting from the other species but at the same time the other species won't be harmed nor would they benefit from me. Usually it means you can get a free meal, shelter/protection, maybe even a free ride, and in the process I won't be harmed by the other species. Hope that helps! :)
