The correct option is B Filtration, Re-absorption, Secretion
Three processes involved in urine formation are glomerular filtration, reabsorption and secretion. Filtration of blood by the glomerulus is called glomerular filtration, absorption of selected materials from the filtrate into the blood of the peritubular capillaries or vasa recta is called reabsorption and excretion of additional wastes from the blood stream into the filtrate is called secretion.
