—Do you know Jack quarreled with Tom?
—I don't know, .
A. so don't I care
B. nor do I care
C. I don't care neither
D. I don't care also

A. so don't I care(答案→)B. nor do I careC. I don't care neitherD. I don't care also解析：句意：--你知道杰克和汤姆吵架了吗？--我不知道，我也不关心。so表示上面的情况也适合另一者时，前面的句子需是肯定句，故排除A；nor或neither可以表示上面的情况也适合另一者时，前面的句子需是否定句，并且用部分倒装。also不能用在句末。故选B。

你的回答很对
