Detailed explanation-1: -Answer and Explanation: The following statement is false regarding B cells: Memory B cells are the antibody-producing B cell types.
Detailed explanation-2: -B cells can have anti-tumor activities through the recognition of tumor-specific antigens and antibody production, antigen presenting cell (APC) function or direct killing of cancer cells.
Detailed explanation-3: -B cell activation occurs in the secondary lymphoid organs (SLOs), such as the spleen and lymph nodes. After B cells mature in the bone marrow, they migrate through the blood to SLOs, which receive a constant supply of antigen through circulating lymph.
Detailed explanation-4: -The correct answer is option a because memory B cells are made from a subset of B cells that remain after an adaptive immune response to an infection and do not produce antibodies, that is the job of the differentiated plasma cells.
