The figure below shows the relative concentration of polychlorinated biphenyls (PCBs)in several members of a lake food web.
Although the lake trout and minnow are both fish, the lake trout is more contaminated. Why?

A)Lake trout are bigger so their bodies can store a greater quantity of PCBs.
B)PCBs dissolve poorly in water but readily in fat; lake trout have a higher percentage of body fat than minnows.
C)Lake trout are large and long-lived; when they respire they pass water over their gills allowing the PCBs in the lake to accumulate in their bodies.
D)Lake trout fed on minnows, whereas minnows fed on crustaceans.
