The correct answer is:
**c. the wolves increased the population by eating beavers' prey.**
The reintroduction of wolves to Yellowstone National Park helped to regulate the populations of herbivores, such as elk, that were overgrazing the landscape. With fewer elk, the willow and aspen trees were able to regenerate, which in turn provided better habitats for beavers. As a result, the beaver population increased due to the improved availability of food and building materials.
