The graph shows the variation in the population size of finches living on one of the Galápagos Islands. The finches' only food source is seeds found on the island. The seed abundance on the island during the same time period is shown.

What explanation can be constructed based on the evidence in the two graphs?

A
Higher seed abundance results in a lower population size of finches.

B
Lower seed abundance results in a greater population size of finches.

C
Higher seed abundance results in a greater population size of finches.

D
Changes in seed abundance do not affect the population size of finches.
