—Who should be responsible for the accident?
—The boss, not the workers. They just carried out the order .
A. as telling
B. as are told
C. as told
D. as they told

A. as tellingB. as are told(答案→)C. as told D. as they told解析：本题是考查状语从句的省略的问题。根据句意可知，应该是被告知的。排除A，当状语从句主语和主句的主语一致，并且状语从句的有个be动词时，可以将状语从句的主语和be动词同时省略，故选C。即as told. they are 可以省略。
