Answer:
Here's the answer to the best of my ability..
You're asking for what sentence is missing a hyphen and I see nothing wrong with the one sentence that doesn't have a hyphen.
But if you're asking for what sentence is using a hyphen incorrectly then option B is your answer because machine gun doesn't need a hyphen.
If you're asking which sentences are using the hyphen correctly then option's A, and C are your answer.
If you're the question you asked has no mistakes then the best answer would be option D because that's the only option without a hyphen.
Hope this helps.

Agreement is a mixture of both parties stating their needs and wants, and through discussion and compromise. It’s finding a common ground where both parties are happy and satisfied with the outcome.
Sorry if there are any words misspelled. I hope this helps :)
