The correct option is D They should consider the cultural and historical context in which an oral narrative was created before arriving at an interpretation of such a narrative.
"Oral narratives are no more likely than are written narratives to provide a disinterested commentary on events or people. Moreover, the stories people tell to explain themselves are shaped by narrative devices and storytelling conventions, as well as by other cultural and historical factors, in ways that the storytellers may be unaware of." These sentences support option D as the answer. The other choices do not fit the context.
