Answer:
D). Setting.
Explanation:
A memoir is demonstrated as a biography or a book that factually accounts for the personal experiences of a subject from either the personal knowledge or the personal sources about the subject. It is usually centralized upon a specific theme or element of the subject's life.
As per the question, the component that would not represent a key component in understanding a 'memoir' would be 'setting' as it is entirely based on personal experiences and personal knowledge of the subject and contracted over a specified theme. Thus, 'setting' would not be an essential element for understanding it. Therefore, option D is the correct answer.
