我觉得都是可以的

the number of salmon has been reduced by个人认为也是可以的，number的单复数不是问题，关键是后面谓语配合就好。
A's B和 B of A感觉ETS没有特别的偏好，也没有见过题目两个选项只有这个区别的，所以还是得具体题目具体分析。
The World Wildlife Fund has declared that global warming, a Phenomenon most scientists agree to be caused by human beings in burning fossil fuels, will create havoc among migratory birds by altering the environment in ways harmful to their habitats.

(A)a phenomenon most scientists agree to be caused by human beings in burning fossil fuels,
(B) a phenomenon most scientists agree that is caused by fossil fuels burned by human beings,
(C)a phenomenon that most scientists agree is caused by human beings' burning of fossil fuels,
(D)which most scientists agree on as a phenomenon  caused by human beings who burn fossil fuels,
(E)which most scientists agree to be a phenomenon caused by fossil fuels burned by  human beings,

这里C选项即正确答案是绝对正确的，因为只有它表示了phenomenon由human beings' burning of fossil fuels这个动作导致的。
