是选B.
句子实际可变为：
We may not have proved (to be+n/adj.可省略) great adventurers,but we have done the greatest march ever made in the past ten years.

needn't have done 过去本来不必做（却做了）
may not have done 过去也许/可能不
shouldn't have done过去本来不应该做（却做了）
mustn't 禁止/不许做.表示肯定性推测判断时,要用于肯定句.否定句中常用can、could代替表示推测判断.
按照语义,只有B 最合适.

我们可能并不是最伟大的探险家，但过去十年我们确实取得了巨大的进步。
