Answer:

A) allopatric speciation

Explanation:

  • Allopatric speciation is a type of speciation that is caused due to geographical isolation that results in the separation of the population of the same species that once inhabited the same geographical area.
  • Due to this geographic separation, the species become so isolated that no more gene flow occurs between the two species and therefore, with time new species get formed.
  • The various geographic changes that can contribute to the separation of the two species can be - formation of mountains, islands, water bodies, glaciers, etc.
  • The populations that get separated due to the geographic barriers are subjected to different selective pressures and hence, speciation occurs.
