Are you looking to get a degree just to get the degree, or are you hoping to have it related to your job/career? I would pursue something that a future employer would view as relevant to your career. As far as which one is easiest, it's debatable and would vary from person to person.
/Edit/ I realize that probably didn't help you one bit. Personally, I think Marketing or Communications is a good mix of practicality and being easy.
