Answer:
conflict
Explanation:
The conflict is the central problem of the story and is what the story is about. The theme is the message of the story, so it can't be the answer. The protagonist isn't a problem, the protagonist is the main character.
I was writing a story.
I have written poems.
I have been writing a novel.
I had written a song.
<span>I had been written up for fighting.
</span>
The last one is sort of weird, since you can't say "I had been written" in the sense of the verb "write" as it would be grammatically incorrect.
I’m gonna say b) because it’s the third one
I would think the first one.
