How are neutrophils targeted from the blood vessels to the sites of inflammation? A. they bind to antigens presented by infected vascular endothelial cells B. they respond to signaling molecules released at the site of inflammation C. they are attracted to DNA or RNA fragments leaking into the blood vessel at sites of inflammation D. they sense nearby disturbances in the body's physiology
