I can think only B is correct. But in the exam says B and F both are correct. How stateless session beans can have instance variable state.
The term �stateless� signifies that an instance has no state for a specific client. However, the instance variables of the instance can contain the state across client-invoked method calls. Examples of such states include an open database connection and an object reference to an EJB object.
