Question

Fill in the blank with the most appropriate option:
Our suitcases ___________ examined before anybody said anything.

• A. have been
• B. Is being
• C. can't
• D. had been

Answer 1

The correct option is D had been

The past perfect continuous (also called past perfect progressive) is a verb tense which is used to show that an action started in the past and continued up to another point in the past. Here, the action of suitcase examination has been continued upto anybody saying anything. The past perfect continuous is formed using had + been + present participle. Hence, Option D is correct. The rest of the options do not adhere to this rule, hence incorrect.
