which of the following is the best description of the bond between oxygen and hydrogen in a water molecule…

Brief Explanations:

Oxygen is more electronegative than hydrogen. In a water molecule ($H_2O$), the electrons in the $O - H$ bonds are not shared equally. This unequal sharing of electrons creates a dipole moment, making the bond polar covalent. Non - polar covalent bonds have equal sharing of electrons between atoms with similar electronegativities, and ionic bonds involve a complete transfer of electrons. Since the electrons in $O - H$ are shared but unequally, it is not non - polar or ionic.

Answer:

polar covalent
