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.
I think it is b the verb tense are constant ask others before you pick ur answer not 100percent sure
