Correct Answer:
B. Were the clothes ironed by her?
This question requires changing an interrogative sentence from active voice to passive voice. The original sentence, "Did she iron the clothes?", is in the simple past tense. In passive voice, the object "the clothes" becomes the subject of the sentence.
For simple past tense interrogative sentences, the auxiliary verb "did" changes to "were" or "was" depending on the subject, followed by the past participle of the main verb. Since "clothes" is plural, the correct auxiliary is "were". The past participle of "iron" is "ironed".
- Active Voice: Did she iron the clothes?
- Passive Voice: Were the clothes ironed by her?
- Tense: Simple Past Interrogative.
Therefore, the correct answer is: "Were the clothes ironed by her?"
