Final answer:
A hydrogen bond in water is the attraction between the partially positive hydrogen atom of one water molecule and the partially negative oxygen atom of another, a result of water's polarity.
The correct option is A.
Step-by-step explanation:
The hydrogen bond in water is described by B) Attraction between the hydrogen of one water molecule and the oxygen of another. This type of bond is a special category of dipole-dipole interaction, where the partially positive hydrogen of one water molecule is attracted to the partially negative oxygen atom of a neighboring water molecule.
This attraction is due to water's polar nature, in which the electronegative oxygen atom attracts the electrons more than the hydrogen atoms, creating areas of partial positive and negative charges which allow the formation of hydrogen bonds between different water molecules.
The correct option is A.
