问题补充：

breaks the law should be punished .

A. Those who

B. Whomever

C. No mattter who

D. Whoever

答案：

A. Those who

B. Whomever

C. No mattter who

(答案→)D. Whoever

解析：句意：违法的人必须受到惩罚。No mattter who 引导让步状语从句，故排除C；should be punished它的主语必须是人，Whomever是宾格，，故排除B；who引导的是定语从句，代替those，所以定语从句的谓语动词应该用break，故排除A。Whoever=anyone who,故选D。
