While a huge amount of money ___been spent stopping pollution , large quantities of water_ _still heavily polluted. A.have; is B.has ;are C.have; are D.has ;has

B

考察主谓一致,a huge amount of money是不可数名词,故后面用单数第三人称形式。large quantities of water大量的水,这里的谓语动词要和前面的quantity一致,quantity是单数 后面谓语动词就用单数 quantity是复数(也就是quantities)  后面谓语动词就用复数。故选B。
