Answer: Hi there! I'm sorry that you've had such a tiresome day, but I'm here to help! I believe your answer would be B (plot).
Explanation: Plot a literary device that writers use to structure what happens in a story. Unlike all the other options, it must present an event, action, or turning point. All three of these can create conflict or raise a dramatic question, which leads to later events that resolve said conflict and/or burning question.
