E must be true. We can map the following causal chain of events from the passage:
nutrient-rich sewage >> pollute coastal estuaries >> overnutrification >> lots of algae >> possibly feeds toxic microorganisms >> most of the fish in the estuary die
We can see that the possibility that (E) presents must be true, if the statements in the passage are true.
Option D is close but it not the only condition so it can be false and need not be true for this argument.
