Hello, I'd say the answer is - regional dialect. "Ethnic dialect" is the way a certain ethnic group speaks in. And "social dialect" is the manner in which a certain social group speaks, those groups could be - age groups, professional people, the elderly, etc.
I’m gonna go with the second one.
I believe that the answer is B
It was in middle school between this girl and this other kid, it was down by this creek that was behind the school and the boy stole her jacket, and the girl attacked him, and kicked him, and they were going at it for a good while. A bunch of kids got some videos of it, and i think the girl almost chocked the other kid out XD
anyways, have a great day! <3
