The founder effect occurs when a small group of individuals from a larger population becomes isolated (by migration, colonization, or other factors) and establishes a new population. The selected small group mentioned in option C is not random, and the large group mentioned in options B and E is less likely to experience the founder effect. Therefore, the most likely example of a founder effect event is a random small group of a bird population that migrates to an island and does not return to breed, as stated in option D.
