Answer:
After going through the passage, the details that give it a reflective tone include the narrator's mention of land ownership and also the narrator's thoughts on hunting a bison.
So, the options A and C are the ones suitable to provide the said tone.
Explanation:
Reflective writing is not about a description only. It involves an analysis, the analysis of an idea, event, scene, memory or a passing thought from different perspectives. Along with this analysis, a personal reflection is added which goes on to reveal a meaning or an additional learning.
Here, in the passage the author revisits the plains and the creek which reminds him of a lot of things. To that he adds his personal reflection which divulges what he feels and thinks about the place.
