Answer:
C.
Explanation:
Water is made up of H20. Hydrogen has a positive charge, and oxygen has a negative one, so the water molecule is polar(meaning it has an unequal sharing of electrons). Anyway, when water molecules connect, opposites attract, so the hydrogen(positive charge), is attracted to oxygen(negative charge). This is referred to as a HYDROGEN BOND, and isn't a bond, but an attraction. It allows for all the properties of water, which are essential to life. I could go on, but I don't want to put you to sleep.
