b. they were designed to conserve natural resources and promote sustainability
c. they were built for visually appealing reasons, creating unique arctic architecture
d. they were necessary to endure extreme cold and due to the lack of other building materials

Explanation:

Igloos were used by the Inuit people mainly because they needed to endure the extreme cold in their Arctic environment. Also, in such a harsh and resource - limited area, there was a lack of other suitable building materials. Option A is incorrect as igloos were not for permanent settlements (the Inuit had a more nomadic lifestyle in some aspects). Option B about conserving natural resources and sustainability is not the main reason. Option C regarding visual appeal is not the key cause.

Answer:

D. They were necessary to endure extreme cold and due to the lack of other building materials
