Correct Answer:
A. He was elected president
The correct answer is A: He was elected president. This sentence correctly transforms the active voice sentence "They elected him president" into the passive voice. In the active voice, the subject ("They") performs the action ("elected"). To convert to passive voice, the object of the active sentence ("him") becomes the subject of the passive sentence ("He"). The verb "elected" is in the simple past tense, so the passive form requires the past tense of "to be" ("was") followed by the past participle of the main verb ("elected").
Let's break down the options:
- A: He was elected president – Correct. "He" receives the action, and "was elected" is the correct simple past passive construction.
- B: He elected president – Incorrect. This is active voice, implying "He" performed the election.
- C: He is elected president – Incorrect. This uses the simple present passive, but the original sentence was simple past.
- D: He was elect president – Incorrect. "Elect" is the base form; the past participle "elected" is required.
Understanding passive voice is crucial for varying sentence structure and emphasizing the recipient of an action rather than the doer.
