Out of the following given choices;
A.microorganisms on large fish would decrease
B.cleaners and mimics would interbreed
C.behavior of large fish would change
D. cleaner population would increase
The answer is C. This is because, as a natural mechanism to defend themselves,the larger fish would become averse to all cleaner fish and cleaner-fish-looking fishes because it is difficult to differentiate between the beneficial and attacker fishes. Ultimately the cleaner fish would decrease and the larger fish would become more infested with parasites on their bodies.
