Question 13

Antigen - presenting cells (APCs) are cells that can present antigens to T - cells. Macrophages, dendritic cells, and B cells are known APCs. Neutrophils are mainly phagocytic cells involved in the innate immune response and do not function as antigen - presenting cells.

Regulatory T cells (Tregs) have the function of controlling inflammation and preventing autoimmunity by suppressing the activity of other immune cells. Helper T cells help activate other immune cells, cytotoxic T cells kill infected or abnormal cells, and B cells are involved in humoral immunity.

Answer:

A. neutrophils
