Answer:
Option: a. Inuit
Step-by-step explanation:
Inuit are the indigenous people of the Arctic regions of Greenland, Canada and Alaska. Inuit people live in igloos and wear furs and sealskin to keep themselves warm. They live in a colder region, so it is necessary to remain warm and waterproof with whatever they find in nature. The people survived on fish, seals, and whales in a harsh environment.
