Who saw the thief?a)Who has seen the thief?b)By whom was the thief bee...
The correct answer is option C: "By whom was the thief seen?"
Here is a detailed explanation:
Subject-Verb Agreement:
- The subject "thief" is singular, so the verb "seen" should also be singular. This eliminates options A and D, which use "has" instead of "was".
Passive Voice:
- The sentence is in passive voice, which means the focus is on the action being done to the subject ("thief") rather than the doer of the action.
- The correct structure for a passive sentence is "object + auxiliary verb + past participle + subject". In this case, the object is "thief" and the auxiliary verb is "was" or "were".
- Option B, "By whom was the thief been seen?", is incorrect because it uses the past participle "been" unnecessarily. The correct structure should be "By whom was the thief seen?"
Correct Option:
- Option C, "By whom was the thief seen?", follows the correct subject-verb agreement and passive voice structure, making it the correct answer.
To summarize, the correct question to ask is "By whom was the thief seen?" This question uses the correct subject-verb agreement and passive voice structure.
