单选题 The sales manager of the company suggested more money is to spent in a more effective advertising campaign and better packaging design.
A. is spending on B. will be spent in
C. will be spent on D. be spent on

【正确答案】 D
【答案解析】[解析] 结构应用。
此句是虚拟语气用法。动词suggest后要跟虚拟的宾语从句，宾语从句的谓语要用：动词原形或should+动词原形。此句的宾语从句又为被动语态，所以要用D．be spent on。
