A theme in "The Man Who Would Be King" is the comparison between the imperialism of the British Empire and the motives/exploits of Dravot and Carnehan. The narrator, thus, serves as an intermediary between the world familiar to Victorian British and the setting of Carnehan and Dravot’s adventure.
This is an example of an anecdote because the writer narrates their own experience.
The best answer for the way to focus on the topic of memoir would be D. I hope that this helps
