—Bob, it’s getting cold outside. take a jacket with you?
—All right, Daddy.
A. Why not
B. What about
C. Would you like
D. You’d better not

(答案→)A. Why notB. What aboutC. Would you likeD. You’d better not解析：根据答语All right, Daddy..可知,题干表示的是一种建议,且后面是动词原形由四个选择项的提示可知why not do sth表示问什么不…其后跟动词原形，what about的后面跟动词的ing形式，would you like to do sth其后跟动词的不定式，you’d better do sth表示最好做某事，其否定式是you’d better not do sth其不符合题意故选A。

谢谢了
