Which factor can help in speciation?

Answer and explanation

Correct answer: Geographical isolation

The governing concept is speciation, the formation of new species. When a population becomes geographically isolated, its groups have little or no interbreeding. Mutations, variations, genetic drift and natural selection can then act differently in the separated groups. Over many generations, their differences may become large enough to prevent successful reproduction between them. Therefore, geographical isolation is the suitable factor; the other options are unrelated to the origin of species.
