The forces between water molecules and the bonds between the atoms in the water molecules break.

Answer 1

The first option.

Boiling is a physical change: the intermolecular forces (hydrogen bonds) between water molecules are overcome/weakened so molecules separate into vapor, but the covalent O–H bonds within each water molecule remain unchanged.
