While researching a topic, a student has taken the following notes:

* Yellowstone is a national park in the northwest United States.
* In 1995, gray wolves were reintroduced into the park.
* Since then, the number of gray wolves in the park has stabilized at roughly 100.
* This number is believed to be the park's carrying capacity.
* Carrying capacity describes the maximum number of a species that a specific environment's resources can sustain over time.

The student wants to specify the number of gray wolves in Yellowstone. Which choice most effectively uses relevant information from the notes to accomplish this goal?
