--stay in that hotel.

The correct answer "Never again will they" is appropriate because it maintains proper word order and emphasizes a strong negative sentiment about returning to that hotel. Here’s a breakdown of why this option is the best:

    
• Word Order: The phrase starts with "Never again," which sets a strong tone. Then, "will they" follows, forming a correct interrogative structure which suggests a future action.
    
• Clarity: It clearly conveys the message that they do not plan to return, making it an effective expression of refusal.
    
• Grammatical Correctness: This option follows standard English grammar rules, making it understandable to readers.

In contrast, the other options either have incorrect word order or do not convey the intended meaning clearly.
