A. the more; the little
B. the fewer; the more
C. the more; the fewer
D. the more; the less

A. the more; the littleB. the fewer; the more(答案→)C. the more; the fewerD. the more; the less解析：句意：孩子们，请记住。你月细心，你犯的错误就越少。我们知道，李先生。Careful的比较级是在其前面加more构成。Mistakes错误，是复数名词。Fewer是few的比较级，可以修饰复数名词。More是many或much的比较级，可以修饰不可数名词或复数名词。Less是little的比较级，可以修饰不可数名词。所以选C。
