Final answer:
The incorrectly matched option is 'Platelets - determine blood type' as platelets are for blood clotting, not for determining blood type, which is a function of antigens on red blood cells.
Step-by-step explanation:
The option that is incorrectly matched is b. Platelets - determine blood type. Platelets are involved in blood clotting, not in determining blood type. Blood types such as A, B, AB, and O are determined by specific antigens present on the surface of red blood cells. The role of platelets is primarily in the formation of blood clots to prevent blood loss after injury. Meanwhile, red blood cells carry oxygen and some carbon dioxide, plasma carries nutrients, wastes, hormones, and enzymes, white blood cells are involved in defense and immunity, and B & T lymphocytes are specific types of white blood cells that play a role in acquired immunity.
