Answer:
I think it might be B.
Step-by-step explanation:
I am not a 100% but I came to this answer from slice and dicing. You know it's not C or D. It is either A or B. You know they do make art, toys, clothes, and more, but they make a living off of trade. So I think it's B because they make items for a living to trade mainly.
I hope I helped!
