Except just means that the wrong answers will be of that category, and the right answer will not. So, for a must be true except, the wrong answers will all have to be true, and the correct answer is something that could be false. For a could be true except, the wrong answers all can be true, but the right one cannot be true, or must be false. Similarly for a could be false except, we have four wrong answers that can be false, and once that cannot be false, aka a must be true. Must be false except will have four things that must always be untrue, and then one that could be true.
