What is geographic isolation least likely to give rise to?
A) convergent evolution
B) speciation
C) divergent evolution
D) reproductive isolation
Geographic Isolation
Refers to populations of organisms that are separated from exchanging genetic material with other organisms of the same species by physical barriers.
Convergent Evolution
The process where organisms not closely related independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.
Speciation
The evolutionary process by which populations evolve to become distinct species, through mechanisms such as natural selection, genetic drift, and geographical isolation.

Final Answer :
A
Explanation :
Geographic isolation is most likely to give rise to divergent evolution and speciation, as populations become isolated and adapt to different environmental conditions, leading to the development of new species. It is also likely to give rise to reproductive isolation, as populations diverge genetically and no longer interbreed. Convergent evolution, on the other hand, occurs when unrelated species evolve similar traits because of similar environmental pressures, and is not typically associated with geographic isolation.
