The best explanation for why finches on one of the islands in the Galapagos have large beaks while finches on another island have small beaks is:a. Over time, the finches on the island adapted as a result of competition for resources.

Due to competition for limited resources, the finches with beaks that were better suited to the available food sources were able to survive and reproduce, passing on their advantageous traits to their offspring.

Over time, this led to a divergence in beak size among the finches on different islands, as they adapted to the unique environmental conditions and available food sources on their respective islands.

In summary, the variation in beak size among finches on different islands in the Galapagos is a result of natural selection as a response to competition for resources in their environment.
