问题 Nuclear fuel will be used in the reactor after its ______ into the form of rods.

选项 A、having compressed
B、to have been compressed
C、having been compressed
D、have been compressed

答案 C

解析非谓语动词用法。介词after后应跟动名词作宾语。its指代nuclear fuel，与compress之间为被动关系，且谓语动作used发生在compressed之后，故用动名词的被动完成时having been compressed。
