One person says i am gonna kidnappe d you what i am gonna do now look at his message tell me something

I would say: Setting

reason:

In general the story/plot revolves around the setting. The setting sets up the mood of the story, where the events take place and at what time the events take place. 

Resolution-  doesn't make sense because it is where the problem in the storyline has been solved or the characters have come up with a compromise.

exposition-  with this lit term we are being introduced to characters, possible events, the setting, and other parts of a story such as introducing the theme or themes in a story. In layman's terms, it is background info on a story. 

motif- I believe this deals with same ideas that occur throughout the story...the ideas repeat themselves throughout the story you could say.

Hopefully this helped and good luck.
