Answer:
The answer is C. Sympatric Speciation via polyploidy
Explanation:
Among all various forms of speciation that exist, the most rapid is sympatric speciation which occurs when a population becomes separated in terms of reproductivity. The process of offsprings developing with more than the common number of chromosomes is referred to as sympatric speciation via polyploidy and it is this process that makes this speciation rapid.
