问题补充：

it is! Thank you very much!

A. What valuable advice

B. What a valuable advice

C. How good a suggestion

D. How good advice

答案：

(答案→)A. What valuable advice

B. What a valuable advice

C. How good a suggestion

D. How good advice

解析：考查感叹句。感叹句用what或how引导。感叹句的中心词是名词时，用what；是形容词或副词时，用how。Advice和suggestion都是名词，故用what引导，排除C、D；advice“建议”，不可数，排除B。故选A。
