The correct answer would be the last option.  It is due to proactive interference that she sometimes calls stephen by steve's name. This interference happens when old information would prevent an individual in recalling a newer information. The name of steve which is part of the past for her get in the way in recalling the name of her present boyfriend. Other example would be when you try calling a new number, however, the previous or old number would interfere in your memory so it would be difficult for you to remember the new one. The reverse of this interference is called the retroactive interference.
