Answer:
A. The strange, uncertain ending of the story is meant to evoke questions from the reader.
Explanation:
Let us discuss each option.
Option A:
The sentence holds an element of mystery. The writer, albeit describing the nature of the story's ending, does not reveal any crucial information about the story and hence leaves room for curiosity and intrigue so as to attract readers.
Option B:
The writer plainly explained that there will be fights between the main characters. Such a statement made it obvious that the main characters will be of the contradicting nature.
Option C:
This type of statement easily remove any interest in the piece of writing as the common reader will simply question, "Why read the whole thing when the crucial element occurs in the final 4 paragraphs?".
Option D:
Again revealing information about the main character. Whoever reads this line immediately knows that the main character will be the one described early on and this will reduce reader's interest.
Hence, option "A" is the most aesthetic choice because it gives a peek into the story while keeping all information hidden
