Yeah, the answer is definitely b.assuming that you're a high school student or middle school student, you probably don't need your parents' to pick out your clothes anymore. and i don't know how it works at other schools, but i know that at my high school, you don't get to pick the book you read for an english assignment. your teacher picks that. the decision of what after-school job i should get, i would definitely make with from my parents and other people that i trust. ultimately, the decision is up to me, but i would need advice from people who are more experienced.
