B
第一个固定短语be at a loss表示茫然/不知所措
第二个用the是因为后面的that引导的句子是word的同位语,word是特指的那句话,特指要用定冠词.
句子的意思是：当得知他由于超速被禁止驾驶时,驾驶员完全茫然不知所措了.
另外,这个句子缺了一个词,he后面应该有个was,因为是被动关系.

b
前一个是固定用法，后一个表强调

选B
(at a loss 不知所措
"that he forbidden to drive for speeding" 是"word"的内容,所以用"the"表特指)

本题应该选A. at a loss固定的搭配，意思是：困惑，不知所措。另外，句中地word的意思是：消息，此时word用作不可数名词，因此前面不加冠词。

B
that....为（the word的)同位语，而同位语的对象都是特指，故用the.
