Solution

The correct option is A Isolation
Presence of one or more genomes in addition to the normal for the species is known as polyploidy. It causes fast speciation as it leads to complete reproductive isolation of an individual from other gene pools and it is found in nature due to the failure of chromosomes to separate at the time of anaphase.
