Answer is Right!
Answer is Wrong!
The answer is C. Lamprey.
A rhea is a large flightless bird native to South America. A trout is a freshwater fish of the salmon family. A salmon is a large anadromous fish of the salmon family. A lamprey is a parasitic jawless fish with a sucker-like mouth.
Lampreys are different from the other options because they are parasitic. They attach themselves to other fish with their suckers and feed on their blood. The other options are all free-living fish.
