I’d say C.
A doesn’t make sense, they definitely could’ve domesticated animals in that time.
B doesn’t make sense either, they could’ve easily seen smoke signals, the sky wasn’t filled with them often.
C is just a weird answer. I doubt they were “passive observers” but probably the best answer to the question.
D doesn’t add up because they definitely needed agriculture/food surpluses. They were always hunting, they obviously ran out of food rather quickly.
So C is the answer.
