Coexisting species of wild cats differ in the size of their canine teeth, which corresponds to differences in their preferred species of prey. This outcome is most likely the result of: Competitive exclusion Resource partitioning Ecological release Preemptive competition

The correct answer is - Resource partitioning

Explanation:

According to the competitive exclusion principle, two species can not share the same niche because species that share the same niche have the same needs which leads to the interspecies competition.

This competition leads to resource partitioning which means the species who share the same niche evolved by natural selection to occupy different niche by dividing their resource which leads to the coexistence of two different species.

So here coexistence of wild cats differ in the size of their canine teeth is the result of resource partitioning.
