选择正确答案并说明理由.

本题两个答案都不对。要么说 。。。 what was the matter with her。要么说 。。。 what was wrong with her。出题人希望你选A,疑问句在变成从句后,语序应是陈述语序。如：I don't know who he is。 (Who is he? 变为who he is。 “he"是主语) 出题人以为疑问句“What was the matter with her?" 的陈述语序是what the matter was with her。 把the matter当作了句子的主语,其实不然。"the matter"在句中是表语,还是应该放在be动词之后,"what"才是句子的主语,所以在变成从句后,语序不需改变。B答案中wrong是形容词,只能做表语放在be动词（was）的后面,what是句子的主语,所以此句不存在改变语序的问题。
