Show answer & explanation
Correct answer: B
Explanation
Correct Answer
The results have been announced on the official website by them
Explanation
The original active voice sentence uses the present perfect tense (have announced). When transforming a present perfect active sentence into the passive voice, the structural rule dictates using has/have + been + past participle (V3). The plural object "the results" shifts to the subject position, requiring the plural auxiliary have been announced. Additionally, the original active subject "They" is optionally expressed at the end of the clause through the agentive prepositional phrase "by them," preserving the original tense and semantic intent completely.
Key Points
Word: Have been announced
Meaning: The passive voice transformation of the present perfect active verb 'have announced'.
Grammatical Role: Passive verb phrase (functions to show that the subject receives the action of the verb).
