    wrong wording.

    a human with two X-chromosomes and no Y-chromosome would not be male

    Assuming that you are talking about an X-linked disease in humans, and that you are indicating the affected X-chromosome as "x" and the "normal" x as X, then

    D. xY

    In order to be male, he must have a Y chromosome, so all of the other choices would be females.
