(A) which引导的定语从句缺少谓语动词。
(B) extended被动形式错,句意变成了highway被延伸了,实际上延伸是highway主动发出的动作; extended和over 2500 miles变得没有关系,显然不是合理的句子结构安排。
(C) 整个句子缺少谓语动词;extended被动错句意变成了highway被延伸了,实际上延伸是highway主动发出的动作;in length也是做定语不如long简洁,虽然XXX miles in length的表达形式是正确的。
(D) being使用wordy;in length不如long简洁;was extended变成和was the Incan highway平行,结构不合理,且was extended被动使用不当。
(E) Correct;Extending做状语修饰主句。
