Answer:
The best option is A) Rising Action
Explanation:
In a narrative, a character usually faces several relatively smaller conflicts that create tension throughout the story until a final moment comes when the main conflict is solved. This development of obstacles and the attempts to overcome them complicates the plot, gaining momentum and building up tension for the climax. Such development is known as rising action.
Thus, rising action is everything that takes place between the beginning of the story (exposition) until the its peak moment, the major conflict (climax). Falling action would be the opposite of rising action, taking place after the climax and being characterized by a decrease in tension. Denouement or resolution is the conclusion of the story, its closing.
