Read the Following Scenario and Answer the Question Below

Read the following scenario and answer the question below.
In 1906, President Theodore Roosevelt created the Grand Canyon National Game Preserve on the Kaibab Plateau in northern Arizona. Between 1907 and 1923, cattle grazing was greatly reduced, mule deer hunting was eliminated, and predators were killed. Over 800 cougars, 20 wolves (most had already been killed in the 1800s) , and 7000 coyotes were trapped or shot. In response, the mule deer herd began to increase: By 1915, deer numbers were estimated at 25,000; 50,000 by 1920; and 100,000 by 1923.
-Which of the following is likely to have occurred after 1923?

A) The government has continued the ban on deer hunting and has continued killing cougars and coyotes that immigrate into the preserve.
B) The deer overgrazed their environment, decreasing the carrying capacity of the habitat.
C) The deer population crashed, and no deer have been seen in the preserve since 1947.
D) The preserve was invaded by Eurasian collared doves in 1988.
E) The deer population continued to increase exponentially until 2002.
