In the question below, fill the gap with the most appropriate option:

The trader complained that he _____ robbed

Answer Details

The correct option to fill the gap is "had been". "Had been" is in the past perfect tense which is used to show that an action was completed before another past action. In this context, the trader is referring to a past event of being robbed before complaining. Hence, the past perfect tense is appropriate.
