C) Dendritic cells.
Explanation:
Dendritic cells are types of immune cells that carry out immune responses by presenting antigens on its surface to other immune system cells.
They are derived from the bone marrow and have tree-like structures. Dendritic cells are found in the skin, lungs, nose stomach and intestines. They are phagocytes and are antigen presenting cells (APCs).
Dendritic cells work by capturing the antigens from foreign bodies and processing and presenting these antigens on their cell surfaces for recognition and action by other cells of the immune system.
