首先B和C都是对的,意思都是一样的.
‘d better=had better+(not)动词原形--------最好(不).
该处是省略to的不定式,是不能用to 的.

答案C
此题考查句意理解能力。had better后接动词原形,否定形式在动词原形前加not。B选项不符合语境。
希望对你能有所帮助。

C.leave后面少了here
D.You'd better 后面是加动词原形,或not 动词原形。

had better do sth. 所以D错误;
如果谓语动词是终止性动词,并采用“... not ... until ...”结构,意为“……到……时候才……”。在这里不合适,所以不能选c
