A. we got here in his car

B. we got here by car

C. in whose car we got here

D. by whose car we got here

答案：

A. we got here in his car

B. we got here by car

(答案→)C. in whose car we got here

D. by whose car we got here

解析：考查非限制性定语从句。句意“布朗先生是这家公司的经理，我们坐他的车来这里的。”by后加交通工具，不能与冠词连用，in one’s car“坐某人的车”，in后可以加冠词。故选C。
