mast cells phagocytes B-lymphocytes T-lymphocytes
I gave my students this multiple choice question: Some immune cells are actively involved in ingesting, destroying, and presenting invading microbial antigens on their surface to stimulate other cells to produce antibodies. Which of these cells is responsible for initiating such an immune response?

Only one answer is correct among these 4 choices:
- mast cells
- phagocytes
- B-lymphocytes
- T-lymphocytes

Could you tell me which one is correct?

phagocytes
