our friends expected to assume the burden of their own defense,_theg are competent to do.
which we are certain
that we are certain of
of which we are sure
for which we are sure
for which we are sure

这里是把of 提前了~把它理顺就是：which we are sure of.这里be sure of 是固定搭配,意思是："对……表示肯定" ,再有,这个句子是很典型地考察定语从句的用法.
首先,横线前面有个逗号,逗号后面不能用that ,所以B排除.
其次,A选项的which 前面应该加一个of ,意思跟 be sure of 一样.
再次,C和D的 which 前面用了 for 是不对的,没有 be sure for 这种说法~
感觉你问这个问题应该是语感欠缺,多背背文章吧~个人感觉新概念的文章很不错,句式都很优美,而且对语感的培养极其有帮助~培养语感比什么都重要~加油!
希望对你有所帮助哈 ：） 呼呼~累死啦~给点分嘛~
