Fire destroyed the top floor of the building:
Correct answer: D. The top floor of the building was destroyed by fire.
- A. The top floor of the building got destroyed by fire
- B. By fire was destroyed the top floor of the building.
- C. Destroyed by fire was the top floor of the building.
- D. The top floor of the building was destroyed by fire.
Explanation
Option D is correct because it adheres to the rules of forming passive voice: the object of the active sentence ('the top floor of the building') becomes the subject of the passive sentence. The verb 'destroyed' is correctly paired with the auxiliary verb 'was' to form the past tense passive voice. Options A, B, and C are incorrect due to improper sentence structure and verb usage. Option A uses an informal construction, Option B misplaces the subject and verb, and Option C incorrectly orders the elements of the sentence.

About Active and Passive Voice
Active voice presents the doer as the subject, while passive voice presents the receiver of the action and uses an appropriate form of “be” with the past participle. Questions cover tense changes, modal verbs, omitted agents and sentences that cannot be passivized because they lack a suitable object.
