what do b cells produce?
white blood cells
bacteria
antibodies.
t cells
hormones

Explanation:

B cells are a type of white blood cell in the immune system. When activated, they differentiate into plasma cells. Plasma cells are responsible for producing antibodies. Antibodies play a crucial role in the immune response by binding to specific antigens (such as those on bacteria, viruses, etc.) to neutralize them, mark them for destruction, or help in their removal from the body. White blood cells are a general category that includes B cells, so B cells don't produce white blood cells. Bacteria are single - celled microorganisms and not produced by B cells. T cells are another type of white blood cell (a different subset from B cells) involved in cell - mediated immunity and are not produced by B cells. Hormones are chemical messengers produced by endocrine glands (such as the thyroid, pituitary, etc.) and not by B cells.

Answer:

Antibodies.
