Climax is the second plot point when the confrontation of a story gets resolved. So it’s not that one.
Dramatic Irony is when the audience knows something that a character in the story does not. Doesn’t seem right either.
Drama is a genre. But you can also have a dramatic action in the story as well - normally some conflict that alter the perspective, physical well-being, while continuing the story. So not that either.
Parallel plots is left. It is a circular definition that plainly describes multiple plots experience a similar set of actions. It may or may not be happening in unison. This is the correct answer
The author might create tension in a story to give the reader that feeling that something is going to jump out or just to give us a feeling of worry for a character.
