The correct answer is Weak Hydrogen Bonds.
In liquids, molecules are generally held together by various types of intermolecular forces, including hydrogen bonds, van der Waals forces, and dipole-dipole interactions. While not all liquids involve hydrogen bonds, for those that do (like water), weak hydrogen bonds are the primary intermolecular forces maintaining the liquid state.
Ionic bonds and metallic bonds are typically found in solid-state compounds rather than in liquids. Condensation bonds is not a standard term used to describe intermolecular forces.
