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 energy provided weakens the intermolecular forces (hydrogen bonds) between water molecules, allowing them to escape into the gas phase (steam). However, the covalent bonds between the atoms within the water molecules (H2O) remain intact.
