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.
Answer:
stage directions
Explanation:
Out of these options, the only characteristic that appears in plays but does not appear in novels are stage directions. Stage directions are instructions that allow a director to present the play in a theatre in the way in which the author originally envisioned it. This includes guidance in terms of background, movements, facial expressions, setting, etc. As novels are not generally intended to be performed, stage directions are not necessary.
