Frequency-dependent selection involves the fitness of a phenotype depending on its frequency relative to other phenotypes in a given population. Choices A, B, and C all describe scenarios where the success or survival of an organism is influenced by the prevalence of certain traits or behaviors, which aligns with the concept of frequency-dependent selection. Choice D, however, describes a situation where the lack of antipredator skills in New Zealand birds is not related to the frequency of those traits within the population but rather to historical isolation from predators, making it not an example of frequency-dependent selection.
