Correct answer: (d) one species->geographic isolation->divergent evolution->reproductive isolation->two species

Rest three options are incorrect. This is explained below

Speciation is a naturaly controlled evolutionary affair that forms two well defined species. It occurs slowly depending upon the factors responsible for it. It can be divided into following steps: some part of the species move away from the rest due to climatic, natural factors. This helps the separated species to adapt to the present habitat slowly and steadily. Once their survival is not at risk and they adapt to the present habitat, they develop few changes that is best suited to survive there as a part of evolution. Thus, finally when these two separated species somehow meet each other, they would be in a stage not possible to interbreed among themselves, as already they have become two different species with defined traits.
