Could you explain a little more clearer please?
I believe it's B, parentheses.
Comment the correct answer.
B: Independent Clause. This sentence can stand alone as a complete thought.
From the options given, the statement that best explains the given phrase is this: WEALTH MAKES PEOPLE VIRTUOUS. The reference made to the inability of an empty sack to stand upright also lends to this, because when a sack is filled up, it becomes easy for it to stand upright. That is to say, may a man has wealth, it's easy to be virtuous.
