The relevant ______ . documents for the contracted goods are now with us and you are expected to collect them upon the advice.
A、negotiation
B、negotiating
C、renegotiation
D、renegotiating
【正确答案】：B
【名师解析】:在句子 "The relevant ______ . documents for the contracted goods are now with us and you are expected to collect them upon the advice." 中，空缺处需要填入一个名词，因为 "documents" 是名词复数形式，前面的空缺处也应该是名词。选项A、C和D都是名词的变体形式，但它们的含义与句子的语境不符。选项B "negotiation" 是名词，表示“谈判”，但在这个句子中，正确的形式应该是现在分词 "negotiating"，因为它与 "documents" 形成逻辑上的主动关系，表示这些文件与正在进行的谈判相关。因此，正确答案是B "negotiating"，表示“相关的谈判文件”。
