The correct option is <em>B) Some wolves may have had variants in their digestion that allowed them to eat wheat, rice, barley, corn, and potatoes and so were able to survive with humans.</em>
Explanation:
Organism of a population might have genetic variations in them due to many reasons. The species of a population which are better adapted to live in a particular area are able to survive and produce more offsprings. As a result, that particular area increases in that genetic variant.
In the above scenario, some of the wolves had variants in their digestion which made them better adapted to live with the humans as they could eat wheat, rice etc. The wolves which did not have variants in their digestion couldn't survive in the human areas.
