选A. 如果愿意，就说That would be nice,thank you.或Yes,please.如果不需要，那就直接说No, thanks.或者口语说法也可以说No，I'm good.
would you like+名词？表示征求意见，其肯定答语常为：Yes, please. 否定答语为：No, thanks.
would you like to do sth.?表示客气的表示请求。其肯定答语常为：Thanks / I’d love / like to.否定答语为：I’d like / love to, but….
Would you like…?与Do you want…区别：
Would you like …?语气委婉，表示礼貌；Do you want …?用于好友和家庭成员之间。
望采纳谢谢！
