A species inhabiting different geographical areas is

Concept: An organism’s habitat is the place where they live. This includes their external environment. The phenomenon of living and surviving in a certain geographical location is called inhibition.

sympatric speciation: these groups have same ancestral population that evolve into separate species without any geographical separation.

Allochronic speciation: a mode of sympatric speciation in which the differentiation of populations is primarily due to a phenological shift without habitat or host change.

The organisms that are capable of inhabiting different geographical locations have a higher ability to adapt to their external environments. They are called allopatric species. Allopatric species usually get separated because of various natural barriers such as mountains and oceans. This geographical isolation often leads to reproductive isolation which eventually leads to the formation of a completely different species. This process is called speciation.

Hence the correct answer is option D.
