Answer: Grammar police here :) it makes perfect sense and it belongs there so good job :)
Explanation: Famous writers like Angie Thomas and many more use sentences like this to explain the characters emotions and show it better. Using “I froze” like that in a sentence helps the reader better understand what’s going on by putting periods because periods symbolize a pause and that perfect for it, “...when the loudest noise I had ever heard traveled down the hallway *pause* I froze” see what I wrote there wouldn’t be correct but like I said a period symbolizes a pause in a sentence or the end of it so it would be “...when the loudest noise I had ever heard traveled down the hallway. I froze.” See how it makes a bunch of sense. I hope it does. Lol. Hope that helped :)
"During the rock concert" would be the subject, as "an amplifier exploded on stage" would be the predicate.
The middle one is the right answer.
