Which of the following would not be considered a sports facility?

A lake would not be considered a sports facility because it does not meet the criteria of being a constructed or designated space specifically designed for organized sports or athletic events. While a lake can host a variety of recreational activities, such as swimming, kayaking, or fishing, it lacks the infrastructure and management typically associated with sports facilities, like seating, permanent structures, and amenities specifically built for spectator sports or organized competitions. On the other hand, a stadium, gymnasium, and sports complex are all built environments that are explicitly designed to accommodate sporting events, provide seating for spectators, and offer necessary facilities for athletes.
