Three Rooms

Question: Setting - olden days (Kings, Queens, Knights, etc), middle of a very cold winter. A spy gets trapped in a snow storm and gets lost. He decides to choose a direction and go straight in that direction. He ends up at a castle, knocks at the gates and gets let in only to find it is the enemy castle. He gets tried and is sentenced to death. He is going to be sent to one of three rooms for a few hours. He does gets to choose the room. The first room is a deep hole filled with water and crocodiles with sheer walls and nothing to hold onto, the second room is filled with lions that haven't eaten in three days, and finally room number three is filled with various tortures (with people to operate them) and two keys, one for each of the other two rooms. Which room is safest for him?
