Reference explanation:
Correct answer: A
The past perfect is used to talk about an event that happened and completed before another action in the past.
The action “had been standing” happened continuously before the action “let us go” took place, so it is conjugated in the past perfect.
When they let us go, we stood outside the exam room for more than half an hour.
