Question

She admitted her mistake when she for ........................... hours by the police.

• A. had interrogate
• B. was interrogated
• C. is interrogated
• D. have been interrogated

Answer 1

Answer:

B. was interrogated

The sentence is in the past tense, and it uses the passive voice — she is the one being interrogated (not the one doing the interrogating). So we need the past passive form:

• was interrogated = ✔️ correct passive past tense
