请教一道语法题opponents argued that those (who have filed were)/(filing were) 括号内为画线部分大

6．还有一道题大概如此 proponents of bill argued that the people who have not filed to bankrupt were... benefits, but the opponents argued that those (who have filed were)/(filing were) 括号内为画线部分

说最近的什么suggest the interest for the matter of A , B , and C. 答案好像有 for the matter of A, including....； for the matter of A such as; in the matters of...感觉考 interest 后面的介词
   以及用such as 还是Including

大家分析一下选哪个？为什么？
