The correct answer is B. A reporter tries to piece together the truth as she listens to three different plane-crash survivors tell their stories.
Step-by-step explanation:
The frame narrative is a literary technique that occurs when there is one main story and this leads to one or more narratives that appear inside it which is called a story within a story and implies besides the plot development of the main narrative there are more narratives that also develop and are part of it. This can be seen in the case of "A reporter tries to piece together the truth as she listens to three different plane-crash survivors tell their stories" because in this the main story or narrative is the reporter trying to understand the truth of the crash and each of the testimonies from the survivors act as a narratives that develop within the main story.
