I believe the correct answer is D. humorous and informal.
You can see in the excerpt that the narrator is talking about him/herself in a humorous manner by mentioning his/her eccentricities such as 'mismatched socks' etc. The tone is very light and funny, so A, B, and C would be incorrect answers.
Answer:
The fear of appearing foolish to the Burmese causes him to kill the elephant.
Explanation:
The narrator believes the elephant is valuable, almost like a "huge and costly piece of machinery." He realizes that soon the animal will calm down and won't be dangerous anymore. He does not want to kill the elephant, but the natives are excited to see the beast shot. And so the narrator realizes that he is now compelled to shoot the elephant. At the end of the story, Orwell wonders if any of his comrades understood that he killed the elephant “solely to avoid looking a fool.”
