Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Has the calibration issue been resolved by the engineers yet? .
About the given sentence: Type of sentence: Interrogative Tense: Present Perfect tense Given voice: Active voice Subject: The engineers Object: The calibration issue
Structure for conversion: Active: Has/Have + subject + verb (IIIrd form) + object + ...? Passive: Has/Have + object + been + verb (IIIrd form) + by + subject + ...?
Changes required:
Object as Subject: The object of the active sentence, the calibration issue, becomes the subject of the passive sentence.
Helping Verb: Since the calibration issue is singular, we use the helping verb has instead of have.
Passive Marker: In the Present Perfect tense, the word been must be added between the new subject and the past participle of the verb.
Verb Form: The third form of the verb (resolved) remains the same in both active and passive for this tense.
By + Agent: The original subject, the engineers, is introduced using the preposition by.
Converted sentence: Has the calibration issue been resolved by the engineers yet?
Hence, the chosen option is correct.
