Correct Answer:

Option A – had been

Explanation

the trader ”complained” is a (past tense) and (past participle). this means that, the event had already taken place in the past.

the word ”robbed” is in its past tense as well.

had is also a (past tense) and a (past participle) mostly used to narrate an event or experience undergone in the past. it rightly completes the space on the question.
