The correct answer is option A. "the beginning". In literature, a falling action is defined as the events that happens right after the climax has ended. In the beginning of "The Black Cat" by Edgar Allan Poe the narrator addresses the audience to explain why he is gonna lose is life tomorrow, this implies that the story starts when the climax has ended and the narrator is gonna explained what happened.
A, B, and D begin statements that can stand by themselves logically. C begins a statement that shows how the previous statement and itself are connected. As such, the answer is C(As a result).
I believe the answer is heroic couplets, which is a traditional form for English poetry, commonly used in epic and narrative poetry, and consisting of a rhyming pair of lines in iambic pentameter.
