Solution

The correct option is C Gene flow does not occur between populations of a species.
Gene flow within a population can introduce or reintroduce gene versions to a population, increasing the genetic variation of that population. Gene flow across populations can make distant populations genetically similar to one another, hence reducing the chance of speciation. The less gene flow between two populations, the more likely that two populations will evolve into two species.
