Answer

Brief Explanations:

Ice floats because hydrogen bonds in water form a lattice - like structure when it freezes, spreading the water molecules apart and making ice less dense than liquid water. Covalent bonds are within the water molecule itself and not responsible for the density change related to ice - floating.

Answer:

The option that says "of hydrogen bonds spreading the molecules out in a lattice causes water to be less dense and thus float" is correct.
