Fill the gap with the most appropriate option from the list following the gap.
My friend _____ me for many years when i met him last week?
Answer Details
The most appropriate option to fill the gap in the sentence is "had not seen." This is because the sentence is in the past perfect tense, which is used to describe a completed action that happened before another past action. In this case, the past action is "met him last week" and the completed action that happened before that is "had not seen." This implies that the speaker's friend and the speaker had not met each other for a long time, possibly years.
