Robert is said------in a japanese company as a salesman for many years.
A have been working B to have worked
C be working D to work

已经发生的事情，不定式要用完成时态。翻译成中文就是：据说罗伯特曾经在日本...。

这句话还可以写成：
It is said that Robert has worked in a Japanese company for many years.

A和C：语法不对

D：有for xxx years，要用完成时态。不对。

B：唯一正确。

A 改为 to have been wroking 也对。
