Answer:
<em>The correct option is b) competition among individuals for available food sources </em>
Explanation:
Natural selection can be described as a phenomenon which describes that organisms which are better adapted to survive in an environment are able to live and pass on their characteristics to their children. Organisms develop characteristics with the passage of time which enable them to survive in different areas. Competition among the finch population led to the development of different finch sizes.

an organism that occupies it's specificed niche will these to increase in size due to the proper conditions at its niche
The Arctic fox would either go extinct or it would adapt to seek out new sources of food. These could be the chicks of seabird colonies or walrus/seal pups. It could also adapt to feed on the young of its competitors. Another feeding adaptation would be to scavenge for dead animals or the kills of other predators. Thess adaptions might require behavioural and/or physical changes to be evolved.
