    for 2 hours vs Until 8 o'clock

    This one is from one of my test.
    "How long will your homework take you?"
    ".........."

    A for 2 hours
    B Until 8 o'clock

    Either of those answers seem plausible for me. Why is it that A is the only correct answer?

    EDIT: It's from a book published by Cambridge. I found the question at this site. The answer is marked in red:

    A, with 'for' is not correct; B is possible.

    Are you absolutely sure? I looked that question up and every source I found said A is the one ("for" included).

    Yes, he's sure. You can say "2 hours," but not "for 2 hours."

    I'm sure, too.

    The book has got it wrong.
