The relationship between Oliver and Whitman and how Oliver perceived Whitman is not provided in the reference texts, therefore we cannot accurately answer the question. The references discuss Walt Whitman's poetry and its enduring influence, but not Mary Oliver's perspective on Whitman.
The question seems to be asking about the relationship between two poets, Oliver and Whitman, and how Oliver perceived Whitman. There might be some confusion due to the multiple choice options given (A, B, C, D) that appear unrelated to the provided reference texts. Since the references provided do not directly address Oliver's thoughts on Whitman, we can assume that this is likely a question from a literature class discussing the views and poems of Walt Whitman, and possibly Mary Oliver's perspective on Whitman's work.
Without specific context or text from Oliver directly addressing her views on Whitman, it is not possible to accurately answer this question. Typically, a tutor would look for the student to have provided specific text or lecture notes that indicate Oliver's thoughts on Whitman. In this instance, it would be inappropriate to speculate on Oliver's views without evidence from her writings or statements.
On a related note, Walt Whitman is known for his use of strong imagery and free verse in poems like "Song of Myself," which celebrated individuality and democracy. His work, particularly the first edition of "Leaves of Grass," was groundbreaking at the time for its content and style and continues to be influential and celebrated. The possible confusion with the relationship between Oliver and Whitman highlights the importance of examining primary sources and understanding the context in which literary opinions and relationships are developed.
