Which of the following is NOT a type of lymphocyte?

Explanation:
Lymphocytes are white blood cells specialized for immune responses, including T cells that coordinate cell-mediated immunity, B cells that produce antibodies, and natural killer cells that provide rapid defense against infected or abnormal cells. Platelets are not lymphocytes; they are small, anucleate cell fragments (thrombocytes) derived from megakaryocytes whose main role is hemostasis—stopping bleeding by forming clots. They don’t engage in antigen-specific immune responses the way lymphocytes do. So the item that is not a type of lymphocyte is platelets.
