To the point of a lot of this discussion, isn't Option A already in operation for most commercial purposes?
Contract law often gets into what is a statement of "material fact" vs. what is a statement of opinion. For example, a company can be sued for a statement like "contains 100% beef" and not for "delicious beef flavor" if the item in question has no beef in it. These torts are different from libel or slander, but they are often upheld in court. Misrepresentations can also be classified into honest mistakes or knowingly committing fraud. I think "most sane people" would argue the ability to sue over false claims of material fact are important commercial regulations.
