The appropriate answer is D. Apex predators are at the top of the marine food chain, where accumulation of pollution is great. 

The concentration of certain pollutants can get amplified as one moves up the food chain. One such pollutant is mercury. Mercury levels have been found to be high in popular fish species such as tuna. Tuna feeds on other fish and mercury is not eliminated from their bodies; it can therefore accumulate overtime. Mercury is harmful to humans as it can cause brain damage and as such pregnant women are advised to refrain from consuming tuna.
