Bill doesn't ___that people say about him.

答案难道没有出错的时候么?这么多人都不去选concern肯定也是有原因的.
你如果还不确定的话 就等开学去问老师吧,问得清楚点.反正选care肯定不会错就对了.
我弱弱地问一句.楼主是不是把 what 误打成that
反正应该是care 关心、在意的意思
Bill doesn't care what people say about him.
他不关心、不在意人们怎么说他.
而我觉得say 是不能换成talk的,原因就在于那个what
what people say about him,换成陈述句语序就是 people say what about him 人们说了些什么关于他的事
而如果用talk就不行了,因为talk about him 意思已经是“谈论他”了,就会多了what,因为不能说 talk sth about him

A
doesn't care,不在乎。
例句
I do not care what you will say about me.
我不在乎你们会说我什么。
say 可以换成talk.
say about ,talk about 意思差不多，不过习惯都用say about

选A
care:在乎，
concern：关注，关心。
Bill doesn't care that people say about him
走自己路让别人说去吧。
在书面英语， talk 极少用作及物动词，除非在 talk 后接用以下的宾语：
Stop talking nonsense.
They are talking busines...

选A. care不在乎别人的评价
concern感觉过于书面
say指用语言表达自己的思想，着重所说的内容。它的宾语只能是“话（语言）”，不是“人”。
talk没有say那么强调
