I don't understand the way_____they worked out the problem.A.which B.on which C.in that D./此题选D,此句是同位语从句，难道that也可以省略么
注意：这里是定语从句,不是同位语从句.
the way后接定语从句的用法,具体用法有三种：
(1)用in which引导；(2)用that引导；(3)省略关系词.此题属于第三种用法.
e.g.The way in which/that/./ he answered the question is surprising.

B 从句缺方式状语 on the way

选A,在定语从句中,要修饰的词是物就用which,the way 在这里指方法

C,in the way ,以某方式。
