In healthy adults, neutrophils represent approximately half of their white blood cells. During a bacterial infection, this number often rises to 80%. One factor contributing to this rise is:
A) Recruitment of neutrophils from tissues into the blood
B) Proliferation of neutrophils at the site of infection
C) Proliferation of neutrophils in the blood
D) Differentiation of blood monocytes into neutrophils
E) Release of neutrophils into the blood from the bone marrow
