题目内容：

No one but you and she wearing a red coat.
A.are B.is

优质解答

B
主谓一致
当主语有with,together with,like,except,but,no less than,as well as 等词组成的短语时,谓语动词与前面的主语部分一致.
例如：
The teacher together with some students is visiting the factory.教师和一些学生在参观工厂.
He as well as I wants to go boating.他和我想去划船.
所以你这题真正的主语是No one 是第三人称单数 所以要选B
