Final answer:
Without the context of the specific literary selection, it's difficult to determine exactly how the author develops the plot. The provided information suggests emphasis on the protagonist's internal monologue and the narrative point of view.
Step-by-step explanation:
Based on the provided excerpts that discuss character development, point of view, and narrative techniques, the statement that best describes how the author develops the plot of the selection might be one that acknowledges the use of internal monologue and point of view. This can be particularly observed where it is mentioned that a character named Bethany describes her thoughts through an internal monologue, indicating a focus on the inner thoughts of the protagonist. Furthermore, considering that there is talk about whether the narrator uses a first person or third person perspective, the development might include the use of a specific narrative perspective. However, without a specific selection to refer to, it's challenging to pinpoint which statement is correct. Therefore, in the absence of additional context about the selection from the original question, it is difficult to provide a definitive answer.
