For me its B, the poor is always in the position of having this fear and worries of what lies ahead. Sometimes even you're striving to lift yourself from poverty, there are hindrance that prevented you to overcome it. If you are not wise and have no strategy to face the reality you cant change the life that you used to.

On the other side, even rich people has also fear to become poor in the future, somehow its unlikely because they have a resources to remain rich unless they're lazy and counting of what they already have. But we know some rich people has no  contentment and still working to secure their future, most of them are into business.
