Which of the following options is the most suitable conversion of the following sentence into active voice?
By whom has this programme been authorised?
Show answer & explanation
Correct answer: A
Explanation
To convert a sentence from passive voice to active voice, we follow these steps:
Identify the Subject and Object: In the passive sentence, 'this programme' is the subject and 'whom' (the agent) is the object of the preposition 'by'.
Determine the Tense: The verb phrase 'has... been authorised' indicates the Present Perfect Tense.
Restructure: In the active voice, the agent becomes the subject. 'By whom' changes to the interrogative pronoun 'Who'. The auxiliary verb 'has' remains, but 'been' is dropped.
Formula for Active Voice (Present Perfect Question):
Who + has + past participle (V3) + object?
