b. The beetle population has few predators in the new habitat.
Explanation:
Based on the scenario being described within the question it can be said that the best explanation for this is that there are few or no predators to kill them off. This is due to the fact that a predator to a certain species kills off a certain portion of the population for food which in term maintains the population of the preyed upon species at an average level, and thus prevents them from exponentially growing out of control like what is happening with the beetles.
