What is the chain of events driven by conflict and decision making in a text? plot characterization setting theme

The correct answer is plot.

Plot is what happens in a particular story - the events that occur, what the characters are doing, how the story begins and ends, etc. The plot of a particular story is affected by various characters, what they argue about, what they decide to do - everything moves the plot forward.

It is the plot of a text that is driven by conflict and decision making, although in some stories this is not the case. In almost all fiction this is true, however.
