The low density of ice compared to water is due to:

Ahydrogen bonding interactions
Correct Answer
Bdipole - dipole interactions
Cdipole - induced dipole interactions
Dinduced dipole - induced dipole interactions

Solution

The density of ice is less as compared to that of water because of the way the hydrogen bonds arrange in the crystalline structure of ice. Ice forms crystals having a hexagonal lattice structure.
When ice is formed, there remain empty spaces in the structure of ice. These empty spaces are due to the directional hydrogen bonds. $$H_2O$$ forms a cage-like structure in solid ice and density is reduced.
$$H_2O$$ molecules form a crystal structure that causes the molecules to be more spread out than they were before.
Hence, the volume occupied is more in the case of ice as compared to that of water.
