I am confused with answer choice C. According to the lesson on sufficient and necessary, the part of the of the sentence that follows unless becomes the necessary and the other part gets negated and is the sufficient. Obviously here both parts are after “unless”, so what would be a better rule to learn this. A tutor taught me that the necessary is whatever is modified by “unless” but I don’t think that helps much here either.
