Explanation:

Primary sources are described as the original or firsthand documents contrary to the secondary resources which are derived from the interpretation of the primary sources. Thus, the primary sources of evidence that Kelly should use in writing a literary analysis on Maya Angelou's poetry would be 'an excerpt from a poem by Maya Angelou' and 'a quote from Maya Angelou’s autobiography' as they exemplify original sources created first handly. Such sources offer support to the claims as they are considered as the most authentic and reliable sources. Thus, options B and E are the correct answers.
