Vedclass · Answer

(C) $T-lymphocytes$ are a type of white blood cell that plays a central role in cell-mediated immunity.They are produced in the bone marrow and mature in the thymus gland,not the thyroid.They do not scavenge damaged cells; that is the primary function of macrophages.There are three main functional types of $T-cells$: cytotoxic $T-cells$ (which kill infected cells),helper $T-cells$ (which coordinate the immune response),and suppressor $T-cells$ (which regulate and terminate the immune response).Therefore,the correct statement is that there are three main types of $T-cells$.
