Which lymphoid cells are responsible for producing antibodies?

• A. T cells
• B. Macrophages
• C. Dendritic cells
• D. B cells

Answer: (D)

Verified step by step guidance

1. Understand the role of lymphoid cells in the immune system. Lymphoid cells are a type of white blood cell that play a crucial role in the body's immune response.
2. Identify the different types of lymphoid cells: T cells, B cells, macrophages, and dendritic cells. Each type has a specific function in the immune system.
3. Learn about B cells: B cells are a type of lymphocyte that are primarily responsible for producing antibodies. Antibodies are proteins that specifically target and neutralize foreign invaders like bacteria and viruses.
4. Differentiate between the roles of T cells and B cells: T cells are involved in cell-mediated immunity, which means they do not produce antibodies but rather help in the activation of other immune cells. B cells, on the other hand, are directly responsible for humoral immunity through antibody production.
5. Conclude that B cells are the lymphoid cells responsible for producing antibodies, as they are the only cells among the options provided that have this specific function.
