[W49] I refuse to accept the blame for something ______ was

翻译：我拒绝接受那些因为别人过错而带来的责难.
1.主句：I refuse to accept the blame for something.我拒绝接受那些因为某事而受到的责难/备.
定语从句：___ was someone else's fault.
2.其中,先行词是something指物,排除指人的关系代词A；
D what不能做关系词引导定语从句,排除.
3.如果先行词是不定代词something等时,则关系代词一般使用that.
而as用于限制性定语从句时,先行词前面必须被such/so/as/the same所修饰才行,此题中没有.
如：I bought the same car as you bought last week.我买了一辆和你上周买的一模一样的车子.
所以正确答案为B.
