    Answer:

    both bonding electrons come from the oxygen atom

    Explanation:

    A coordinate covalent bond is said to be formed when an electron pair is donated into a empty orbital of an atom from a filled orbital of another atom.

    In this type of covalent bond, the shared electron pair is furnished by only one of the bonding species.

    The bonding between H^+ and H2O to form H3O^+ involves donation of a lone pair of electrons on oxygen into the empty 1s orbital of  H^+ hence the two bonding electrons come from oxygen. This is why the bond is called a coordinate covalent bond.
