There are many reasons why some children have bad manners, is the ill information on the Internet and in TV programme．
A. one of them
B. it
C. one of which
D. that

A. one of themB. it(答案→)C. one of whichD. that解析：考查定语从句。本题定语从句的先行词是many reasons，关系代词which指代先行词reasons在句中作为of的宾语。句意：孩子没有礼貌有很多的原因，其中之一就是网络和电视节目中的一些虚假的信息。It不是定语从句的关系代词；that不能引导非限制性定语从句。

谢谢了
