Select the sentence that correctly changes the active sentence into passive voice: "Someone has stolen all the confidential files from the office."
All the confidential files have been stolen from the office by someone.
The active sentence uses the present perfect tense "has stolen", so its passive form must also remain in the present perfect tense.
The present perfect passive is formed with "have/has been" plus the past participle, and since the new subject "files" is plural, the auxiliary "have" is required.
"All the confidential files have been stolen from the office by someone" keeps the tense and the subject-verb agreement correct.
