The correct answer is: Cubic and hexagonal
There are two closely related variants of ice: Hexagonal ice, which has hexagonal symmetry, and cubic ice, which has a crystal structure similar to diamond. Ice is the normal form of ice; ice is formed by depositing vapour at very low temperatures (below 140°K)
