Based on the given diagram, the oxygen atom has two single bonds and no nonbonded pairs of electrons. Therefore, in order to complete the octet and satisfy the valence shell electron pair repulsion (VSEPR) theory, the oxygen atom needs one more bond and two nonbonded pair of electrons, which is option B.
