Which one of the following comparisons between neutrophils and macrophages is true?
A)Neutrophils that enter inflammatory sites can survive for days,but macrophages are very short lived and only survive for hours.
B)Both neutrophils and macrophages are phagocytic and can kill internalized microbes.
C)Neutrophils proliferate at inflammatory sites,but macrophages are terminally differentiated and cannot proliferate.
D)Neutrophils,but not macrophages,express the high-affinity Fc$\gamma$RI receptor,which recognizes specific opsonins bound to microbes and facilitates phagocytosis.
E)Both neutrophils and macrophages contain abundant cytoplasmic granules containing lysozyme,collagenase,and elastasE.

Neutrophils and macrophages can both actively phagocytose and kill microbes,and both express opsonin receptors,such as Fc$\gamma$RI or complement receptors that enhance phagocytosis.Neutrophils are short lived,whereas macrophages can survive for days or weeks.Macrophages are not terminally differentiated and can undergo cell division at inflammatory sites,but neutrophils cannot.Only neutrophils have cytoplasmic granules filled with enzymes,including lysozyme,collagenase,and elastases;these are called specific granules.
