问题 The physicist has made a discovery, ______ of great importance to the progress of science and technology.

选项 A、I think which is
B、that I think is
C、which I think is
D、which I think it is

答案 C

解析逗号后为非限制性定语从句，修饰a discovery，用which连接，I think可视作插人语，故答案为C。引导词which在从句中可充当句子成分，D项中的it多余；that不能引导非限制性定语从句，B不正确。
