B are you
i don't think you are right.叫做否定前移,其实原句是：i think you aren't right.(这种反以疑问句要根据从句的主语和助动词来改)
1.这种句子的反意疑问句要看主句的主语.如果主句的主语为第一人称,那么参考从句来变反意疑问句.如果主句的主语不是第一人称,就参考主句来变.
2.变反意疑问句的关键是“前肯后否,前否后肯”.
3.I think/believe/guess等的宾语从句都否定转移,也就是“否定在前,翻译在后”.
————综上,这个句子的答案应该是I don't think you are right,are you?
