Seattle's osprey population has been declining in recent years, primarily because of hunting, both legal and illegal. Osprey prey heavily on salmon, a fish that is prized as food by the coastal population, who had hoped at least that the decline in the osprey population would lead to an increase in salmon for human consumption. Yet the naturally occurring population of salmon has also declined, even though the annual number caught for human consumption has not increased.
Which of the following, if true, most helps to explain the decline in the population of the salmon?
A. The decline in the osprey population has meant that fishers can work in some parts of lakes and rivers that were formerly too congested.
B. Over the last few years, Seattle's commercial fishing enterprises have increased the number of fishing boats they use.
C. A primary predator of salmon is the American eel, on which osprey also prey.
D. Many Seattle residents who hunt osprey do so because of the high market price of osprey plumage, not because of the threat osprey pose to the natural salmon population.
E. In neighboring stretches of coastline near Seattle, osprey are endangered as a result of extensive hunting.

A B and D irrelevant. E also does not help.
C is giving a reason why salmon could have declined since American Eel is the primary predator. Also since Osprey prey on AE and Osprey population declined hence AE is more and primarily prey on salmon hence salmon's population is declining

I think it should be C.
Given:
1) Osprey prey on Salmon
2) Osprey is being hunted and thus its population has decreased.
3) Expected: Since its hunters are going down, Salmon's population should go up.
Surprise: Salmon's population is also declining. Why?
Pre-think:
In the absence of Osprey, someone else has got a chance to lay hands on Salmon. Some creature X that prey on Salmon but wasn't aggressive enough in the presence of Osprey.
A primary predator of salmon is the American eel, on which osprey also prey.
C it is...
