John and his friends (all 18 year old college students) are walking past one of the recreation centers on campus late one night. Though the recreation center is closed (there is a big sign indicating this), John and his pals decide to sneak into the center to play some basketball. During the game, John slips on a wet spot on the floor and breaks his ankle. John could:
A. Sue the recreation center for negligence and win
B. Not win a negligence suit because he is an invitee
C. Not win a negligence suit because he is a trespasser
D. Win a negligence suit because the recreation center is an attractive nuisance
