The strongest bonds among the options provided are covalent bonds. Covalent bonds involve the sharing of electrons between atoms, resulting in a strong bond.
While metallic bonds can also be strong, they generally do not surpass the strength of covalent bonds. Hydrogen bonds are significantly weaker than both covalent and metallic bonds. "Valence bonds" is not a commonly used term, though it might refer to the concept of bonding involving valence electrons.
So, the strongest bond is covalent bonds.
