red blood cells.
red blood cells.

lymph nodes.

Answer 1

Antibodies are produced by **B cells** (also known as B lymphocytes). When activated, B cells differentiate into plasma cells, which are responsible for the production and secretion of antibodies. T cells, on the other hand, play a different role in the immune response, primarily in cell-mediated immunity. Red blood cells do not produce antibodies. Lymph nodes are structures that house B cells, T cells, and other immune cells, but they do not produce antibodies themselves.
