Answer:
A). That a plot should follow logically from start to finish and feel like everything that happens is necessary.
Explanation:
Aristotle exemplified the plot as one of the six crucial formative elements of tragedy. He describes the plot as 'underlying idea/element of a tragedy' and calls it 'the soul of a tragedy'. He further elaborates plot as an arrangement/sequence of events having a beginning, middle and end.
As per the question, it could be in another way that a plot must follow a logical order from beginning to a conclusion in order to propose a coherence with each and every element so that every action or events seem necessary(as a significant element of the story). The beginning must position an action while towards the middle the action gets intricated leading to conflicts and the conclusion would resolve the issues and offer the story as a complete whole. Thus, option A is the correct answer.
