Correct option is B
Explanation of the correct answer:
The correct answer is Mutualism because this interaction benefits both species involved: the cleaner fish and the larger fish.
Mutualism is an interaction between two different species in which both species benefit. In this case:
Cleaner fish benefit by eating the parasites found on the larger fish.
Larger fish benefit by having the parasites removed, improving their health.
This mutualistic relationship maintains the interaction because both species receive benefits, which enhances their survival and reproductive success.
Additional Information about Incorrect Options:
Option 1 (Kin selection): Kin selection is a form of natural selection where individuals are more likely to help their relatives, even at a cost to their own survival or reproduction, because it increases the chances of shared genetic material being passed on. While kin selection plays a significant role in behaviors like helping relatives, it is not relevant to the cleaner fish-larger fish relationship, where both species are unrelated.
Option 3 (Direct competition): Direct competition occurs when two species or individuals compete for the same resources, such as food, territory, or mates. Cleaner fish and the larger fish are not competing for resources; instead, they have a cooperative relationship where both benefit.
Option 4 (Character displacement): Character displacement occurs when two species evolve different traits in order to minimize competition for resources. It is not applicable to the cleaner fish-larger fish interaction because this interaction is based on mutual benefits rather than adaptation to avoid competition.
