Answer:
d. something is either unique or not unique.
Step-by-step explanation:
Although this expression is very common ("the most unique"), if we take the literal definition of the word unique, it doesn't really make much sense. That because unique means: " being the only one of its kind; unlike anything else." So in the end, you're either unique or not unique. You can't be a little unique or too unique because it doesn't fit the meaning of the word literally. The expression, though, is used to emphasize the uniqueness of the person.
