Detailed explanation-1: -For the example above, the finches on one island do not breed with finches from another island due to the physical barrier between them. Eventually, they will not mate due to changes in behaviors, or will not produce viable offspring due to changes in physiology.
Detailed explanation-2: -So, the correct option is ‘Mule’.
Detailed explanation-3: -The members of the two populations are reproductively isolated due to their adaptations to distinct salt concentrations. An example of reproductive isolation due to differences in the mating season are found in the toad species Bufo americanus and Bufo fowleri.
Detailed explanation-4: -Behavioral isolation occurs when two populations that are capable of interbreeding develop differences in courtship rituals or other behaviors.
