Answer:
The correct answer is "plot."
In the context of dramaturgy, the plot refers to the sequence of events and actions that make up the storyline of a play. The components of a play and its timeline are both elements that contribute to the development and structure of the plot. Conventions and action are also important aspects of a play, but they are not specifically tied to the plot. Conventions refer to the established techniques, styles, or forms used in a particular genre or period, while action refers to the physical and verbal interactions and movements of the characters on stage.
