Answer:
Plot.
Step-by-step explanation:
The plot of any story or narrative is the sequence of events that happen in the story, which shows the themes, the acts of the characters and all that happen in it. It is almost the same as the 'storyline' of the narrative.
The passage begins with the rescue of the maiden by the knight, then their return, the fight with the dragons and the many obstacles they had to overcome. It shows the movement of the story, the progression of the characters and their actions in the story. Thus, the element of drama that correctly classifies the scenario of the passage is plot.
