[Cisspstudy] Bell-LaPadula Question?

[Dallas, Michael J Civ USAF USAFE 100 CS/SCQ]

I received this question in a practice exam provided by a recent ISC2 CBK review seminar.  I was told the correct answer is C, however I don't agree with it as need-to-know would be an important factor with this model.  What do you all think? My guess on this was D.
24.  What is one issue NOT addressed by the Bell-LaPadula model?
            (A)  Information flow control
            (B)  Security levels
            (C)  Need to Know
            (D)  Access modes

Thanks,
Mike
