Alberto Was Attending a Concert at Parker Hall

Alberto was attending a concert at Parker Hall. During the concert Alberto had to leave his seat to go to the washroom. There was some construction going on in the hallway outside the bathroom, so the management had cordoned the area with pylons and yellow tape, and had put up a sign warning patrons to stay out (and pointing to the location of the nearest available bathroom) . Alberto was very much in a hurry to use the bathroom, so he stepped under the tape, tripped on a loose tile, and injured himself. He sued Parker Hall for negligence. Which of the following is TRUE?

B) Alberto voluntarily assumed the risk of an accident by his actions.
C) The defendants took such care as was reasonable in the circumstances to make the premises reasonably safe.

E) All of the above
