Stage directions are things like *enter now* which tell the actors what they should do, however it would be pretty awkward if they read it aloud.
The sentence that adds vivid words to a narrative about the first day of school would be the third option - C. As I trudged toward the building, my knees quivered and my stomach flipped.
The words such as trudged, quivered, and flipped add this vividness to the narrative.
The second one is correct.
I hope this helps!
Feel free to mark brainliest!
