Which of these describe the molecular structure of water?

Which of the following properties can be assigned to water?
I. It has a permanent dipole moment attributed to its molecular structure.
II. It is a very good conductor of electricity.
III. It has its polar covalent bonds with hydrogen on opposite sides of the oxygen atom, so that the molecule is linear.

Statement 1: The water molecule is polar.
Statement 2: The radius of an oxygen atom is greater than that of a hydrogen atom.

What is chiefly responsible for the relatively high boiling point of water?
