Breakdown of the Problem

The question asks to identify the source of antibody-producing cells from a list of options provided.

Relevant Concepts

Antibody-producing cells are typically referred to as plasma cells, which are a differentiated form of B cells. Let's look at the options given:

1. Monocytes: These are a type of white blood cell that can differentiate into macrophages and dendritic cells but do not produce antibodies.
2. T cells: While they play a crucial role in the immune response, T cells do not produce antibodies.
3. Macrophages: These cells are involved in the immune response and can present antigens but do not produce antibodies.
4. Plasma cells: These are the terminally differentiated form of B cells that produce antibodies.
5. B cells: These cells can differentiate into plasma cells, which then produce antibodies.

Analysis and Detail

Among the options, the key here is distinguishing between B cells and plasma cells. While B cells are the precursors, it is specifically plasma cells that are the active producers of antibodies.

Verify and Summarize

Given the definitions:

• B Cells are involved in the initial immune response, and upon activation, they can become plasma cells.
• Plasma Cells are what produce antibodies, hence they are the source of antibody-producing cells.

Final Answer

The source of antibody-producing cells is plasma cells.
