What is the correct passive form of the sentence: "Has someone made all the necessary arrangements?"
Explanation
The correct passive voice form of the question 'Has someone made all the necessary arrangements?' is 'Have all the necessary arrangements been made by someone?' because it maintains the subject-verb agreement and the question format in passive voice. Option A is incorrect as it remains active voice. Option B changes the wording and structure, making it less accurate. Option D is a statement, not a question, and option E is invalid.
