There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.
Answer: Option D.
<u>Explanation:</u>
According to the information that has been given in the question, the Walleye has moved from the east river to some other river. Even though the prey that they have for food which is the yellow perch, then also they move from the east river to the other.
The probable reason for this is that the east river might be polluted. The yellow perch might have got adapted to this pollution and making this survival possible. But the walleye could not adapt to it.

Answer:
B) speciation.
Explanation:
The Galapagos island is known for the different varieties of finches (species of birds) which could be distinguished on the basis of different beak shapes and size.
This is the result of the selection pressure which led to the divergence of the species on the island through a mechanism called adaptive radiation.
Since the adaptive radiation leads to the formation of different species on the same island, the process of formation species is known as the speciation.
Thus, speciation is the correct answer.
