Answer 2

A. Plasma cells

A. Plasma cells- Correct option

• Terminally differentiated B lymphocytes are called plasma cells.
• These cells originate from B cells in the spleen and lymph nodes and some of them migrate to the bone marrow.
• The primary function of plasma cells is the synthesis of antibody molecules, which attach to particular antigens and render them inactive.

B. T cells- Incorrect option

• One of the three primary subtypes of lymphocytes is T cells.
• T cells defend the body against cancerous cells as well as infections.
• T cells develop in the thymus after emerging from the bone marrow.
• In order to fight infection, they are crucial for cell-mediated immunity and the activation of immune cells.

C. Macrophages- Incorrect option

• Macrophages are mononuclear cells that act as specialized phagocytes to eliminate microorganisms that are ill, dead, or hazardous.
• Macrophages are a type of white blood cell in the immune system that ingests particles that other blood cells have identified as antigens.

D. Dendritic cells- Incorrect option

• Dendritic cells are important immune system antigen-presenting cells that alert other effector immune cells to combat invading infections.
• Dendritic cells process antigens as part of antigen presentation to ensure their interaction with the molecules of the major histocompatibility complex.
