Answer:

#"Number 2"#

Explanation:

Water is an extraordinary substance. For such a small molecule, it has an extraordinarily high melting and boiling point. And its peculiarity is to be explained by hydrogen bonding, which acts as a potent intermolecular force.

The most extraordinary property with regard to liquid water is that water as a LIQUID is more DENSE than water as a SOLID, whereas most solids are DENSER than their liquid phases. Hence ice cubes float......on top of your cocktail, or on top of the ocean. And thus we choose #"option 2"#.
