Polar Bears Rely on Arctic Ice Sheets and Icebergs on the Surface

Polar bears rely on Arctic ice sheets and icebergs on the surface of water as a part of their habitat.How would the habitat of polar bears be affected if solid water was more dense than liquid water?

A) Ice would sink rather than float,so there would be no ice sheets or ice bergs.
B) Water would be unable to freeze at all,causing the total loss of polar bear habitat.
C) Permanent ice would form on the surface,creating more habitat for polar bears.
D) Water would stay liquid over a wider temperature range,limiting ice formation.
E) Water would become polar,causing it to freeze more solidly and melt less easily.
