The war has raised questions about the utility of the national guard and reserve organizations, which the Department of Defense finds ______ to U.S. defense needs but which the Congress desires to maintain.
A．ample
B．surplus
C．extra
D．redundant请帮忙给出正确答案和分析，谢谢！
参考答案
正确答案：D
解析：近义词辨析。ample意为“充足的，丰富的”，如：Amplefoodandclothingbyworkingwithourownhands．(自己动手，丰衣足食。)surplus意为“过剩的，多余的”，如：surpluspopulation(过剩人口)；extra意为“额外的，超过的”，如：Wedonotaskforextrapay．(我们不要求额外报酬。)redundant意为“多余的，剩余的”，如：redundantpopulationinthecities(城市中人口过多)。extra和surplus常作定语，修饰名词，故不能用在本句中。
