Answer:
A
Step-by-step explanation:
C usually doesn't help with anything aside from implying how fast the plot is progressing, or a sudden break/ change from the initial storyline, that kind of thing.
B. The surface level topic is always very apparent, it's the underlying topic that requires knowing what's the tone of the text and some other factors to know.
D. The quantity of adjectives used usually doesn't matter as much as the quality of the adjectives used.
So A is the answer I deducted.
