A．As; whose                                                 B．It; whose

C．As; whom                                                 D．It; whom

【回答】

D

【详解】

考查名词*从句和定语从句。句意：我们都知道，那位老科学家，过去生活很艰苦，到了八十多岁还在努力工作。第一空it is known to us all that...是个固定句型，意为“众所周知……”，it在此是形式主语，that引导的从句为真正的主语；第二空为“介词+关系代词”引导的非限制*定语从句，先行词the old scientist指人，作介词for的宾语，只能用whom，故选D。

知识点：非限制*定语从句
