Correct Answer:
B. The task will be finished
The question asks for the correct passive voice of the sentence: "He will finish the task."
The original sentence is in the simple future active voice, indicating an action that will happen in the future. To convert a simple future active sentence to passive voice, the structure is: object + will + be + past participle of the main verb + (by agent).
- B: The task will be finished. This is the correct passive voice. 'The task' (the object) becomes the subject. The verb 'will finish' (simple future active) correctly transforms into 'will be finished' (will + 'be' + past participle). The agent 'by him' is omitted, which is common when the focus is on the action or the recipient.
- A: The task is finished. This is in the present simple passive voice ('is finished'), incorrectly changing the tense from future to present.
- C: The task was finished. This is in the past simple passive voice ('was finished'), incorrectly changing the tense from future to past.
- D: The task has been finished. This is in the present perfect passive voice ('has been finished'), which is the wrong tense and aspect for a simple future action.
