Thanks for the question. This passage and question are definitely tricky! To figure out what the author's referring to with the phrase "personally remembered stories," let's jump to the relevant lines the question stem gives us. The sentence that we're concerned with distinguishes two kinds of processes, a storytelling memory process and a print-oriented culture's memory processes. The storytelling memory processes are used by those who are familiar with the talk-story form of narrative in this context, and so the "personally remembered stories" are from those who have been accustomed to talk-story. (C) defines these talk-story narratives - the memories are all idiosyncratic (or unique) because of what Kingston will remember from each one of the different stories versus what other people might remember.
(A) is wrong because the genre isn't literary, nor is it first-person. Kingston is telling stories about other people, not necessarily her own stories.
(B) is wrong for the second reason (A) is wrong. The stories aren't about Kingston's own past.
(D) is also wrong because "the precise sequences of words" refers to the memory processes of the print-oriented culture, not the talk-story cultures.
(E) is wrong because the "personally remembered stories" aren't referring to the thematic issues in literature.
Hope this helps, and feel free to ask any other questions you might have.
