Answer:
The answer is A - The populations will not be able to interbreed because they are different species and different species cannot interbreed
Explanation:
The population of birds become reproductively isolated because they are different species and different species are unable to interbreed. This is as a result of barriers which are called mechanisms of reproductive isolation which involves mechanisms, behaviors and processes that are critical for speciation. In reproductive isolation the different species are able to live in the same are but their properties and characteristics do not allow them interbreed to produce healthy and sterile offspring.
