Q.B cells that produce and release large amounts of antibody are called (A) Memory cells (B) Basophils (C) Plasma cells (D) Killer cells

The immune system's working cells fall into several categories. Lymphocytes (roughly 20–30% of white blood cells) include B cells, which mature in the bone marrow and, on activation, differentiate into antibody-secreting plasma cells or long-lived memory cells, and T cells, which mature in the thymus and differentiate into helper T cells (which activate B cells via cytokines) and killer T cells (which directly destroy infected or damaged cells). Monocytes and neutrophils are phagocytic cells that engulf foreign material directly; a matured monocyte …
