——.

A. Yes, very much

B. I prefer the former to the latter.

C. What about you?

D. At your service

答案：

A. Yes, very much

(答案→)B. I prefer the former to the latter.

C. What about you?

D. At your service

解析：上句询问个人喜好和偏爱，下句要对此作出选择。B项：前者（不加奶的咖啡）和后者（加奶的咖啡）相比，我较喜欢前者。故B项符合题意。A项答非所问；D项应该先回答自己的观点后，然后可以用what about反问对方的喜好。D项意思为 “愿意为您效劳；随时听候您的吩咐”
