Hi! to answer your question i think it's A. i had this on my quiz before but i don't remember the answer. If my memory serves me correctly i think it A.
I did some research and this is the result I came up with (by research I do not mean a simple search on safari. I have quite the collection of history books!). The Sepik people were located around the pacific and made lots of art, but mostly pottery. I hope this helped :)
