<span>The answer would be: a) Frost-wedging happens when water freezes and breaks rocks.
Normally, the volume of a substance will become lower when the temperature drops but when water becomes ice it will expand. Water that freezes into ice can produce a high pressure from the expansion of their volume. If enough water fills a joint in a rock, the rock might get enough force to fractured or break. This will happens in the area that has a freeze-thaw cycle like in the polar climate.</span>

Explanation: I took the test.
Hydrogen bonds.
The question asks for bonds BETWEEN molecules NOT WITHIN molecules. A covalent bond occurs WITHIN water molecules between hydrogen and oxygen.
Hydrogen bonds occur BETWEEN water molecules; HYDROGENS of water molecules form a hydrogen bond (a type of intermolecular force) with electronegative OXYGEN atoms of other water molecules.
