His parents were teachers in that school, _______ lost their lives in order to save their students in the earthquake. A．none of them B．both of them C．none of whom D．both of whom

D

试题分析：经过分析，可知这个句子中包含一个非限制性定语从句。Them不能引导定语从句，又因为His parents是两个人，表示两者故用both。 点评：分析清楚句子结构是关键，根据关系词在从句中所作的成分以及含义，选择正确的关系词。
