Step-by-step explanation:
The answer is D. Miss Emily participating in the Civil War represents a symbol of "days gone by" to her community. In the story "A Rose for Emily" by William Faulkner, Miss Emily's participation in the Civil War is mentioned as a part of her family's history and is seen as a symbol of the old Southern aristocracy. Her family's past and status are important to the community, and Miss Emily is seen as a representation of this past era. Her refusal to let go of the past and change with the times is also evident in her other actions, such as her refusal to pay taxes and her insistence on keeping her father's corpse in the house.
