The answer is: E

Siderophores such as aerobactin and enterobactin are chelators that trap iron Fe3+. This Fe-chelator complex is actually transported inside the cell. Transferrin and lactoferrin are iron-binding proteins found in blood and milk. Ferric or iron oxide is rust and lipopolysaccharide (LPS) is a microbial cell-wall constituent
