Solution

The correct option is D At atmospheric pressure, ice crystallizes in cubic form, but at very low temperatures, it condenses to a hexagonal form
Ice crystallizes in the normal hexagonal form. However, at very low temperatures it condenses in cubic form. In the normal hexagonal ice each oxygen atom is tetrahedrally surrounded by four other hydrogen atoms.
