Show answer & explanation
Correct answer: B
Explanation
Correct Answer: The side lamps which had been installed by the municipal corporation last year have been broken.
Explanation
• The given sentence has the main clause in the Present Perfect Tense: has broken.
• Structure for converting Present Perfect active voice to passive voice:
• Active: Subject + has/have + V3 + Object
• Passive: Object + has/have + been + V3 (+ by Subject)
• The complete object noun phrase is "the side lamps which had been installed by the municipal corporation last year". Since the head noun "side lamps" is plural, it takes have been broken.
• The vague agent "Somebody" is dropped in the passive form.
• The relative clause (which had been installed...) is already in the passive voice and remains unaltered.
