The correct answer is C. The forces between water molecules weaken and the bonds between atoms in the water are unchanged.

When water boils, the heat adds energy to the water molecules, causing the intermolecular forces (such as hydrogen bonds) between the water molecules to weaken. However, the covalent bonds that hold the hydrogen and oxygen atoms together within each water molecule remain intact during the boiling process.
