platelets and plasma cells.
lymph nodes and lymph vessels.
b cells and t cells.
phagocytes and macrophages.
red blood cells and white blood cells.

Explanation:

Lymphocytes are a type of white blood cell. The two main types are B cells (which produce antibodies) and T cells (which play roles in cell - mediated immunity). Platelets are cell fragments involved in blood clotting, plasma cells are a type of B cell in an activated state. Lymph nodes and lymph vessels are parts of the lymphatic system (organs and vessels, not cells). Phagocytes (like macrophages) are a different type of white blood cell (not lymphocytes). Red blood cells carry oxygen and are not lymphocytes.

Answer:

C. B cells and T cells.
