Which gymnasium is located within the WAC?

McGrath Gymnasium is indeed located within the WAC (Wellness and Athletic Center). This facility is well known for hosting various athletic events and activities for students and the community, making it a central hub for fitness and sports. McGrath Gymnasium typically features a court setup for basketball and volleyball, among other amenities aimed at enhancing the physical education experience of its users. It plays a significant role in supporting the university's athletic programs and fostering a strong sense of community among students participating in sports and recreational activities.

Carter Gymnasium, Adams Fitness Center, and Tonn Hall Gym do not fall under the WAC, which is why they are not the correct answer in this case. Each of those facilities may serve different purposes or have different locations within the campus, but McGrath Gymnasium is specifically associated with the Wellness and Athletic Center.
