The Theme.
Both of these could be the theme because as said on google,
A theme is the inferred stance taken on the central topic or message of a story. Basically the theme is the main idea/point in a story.
Take the book “Hatchet” for example. The theme is survival.
A plot is pretty much where a story takes place.
A topic is basically the small details in a story.
For that reason, your answer would be 3. Themes.
