Analysis of the question:
A: Deferred during first read through of answer choices and ultimately chosen as correct!
B: We have no evidence of traditional items made from sea otter pelts being mentioned in the exemption; the passage states that the exemptions exist for "taking protected animals".
C: Tempting because in the passage, it indicates that Alaska Natives had made many uses of sea otters before the occupation of the territory by Russia in the late 1700s. However, we don't know that the Russian hunters pressured the Russian government to bar Alaska Natives from hunting sea otters. This part is out of scope.
D: Out of scope. No mention of the sea otter population in the passage.
E: Out of scope. We don't know this!
