This reads a little like a logic puzzle, honestly. The middle can't be false, because the first and last contradict the other- but that would be assuming step siblings don't count for the definition. If they did, then the top would have to be wrong.
Either way, 1 and 3 can't co-exist, but 2 and 3 can't either. So for now, assuming sibling and sister is a literal term, 3 is the lie.
