  Oxygen is the most abundant element on the Sun after Hydrogen and Helium. The
intensity spectrum of resonance lines of neutral Oxygen namely O {\sc i} (1302,
1305 and 1306 \AA\,) has been studied in the literature for chromospheric
diagnostics. In this paper we study the resonance scattering polarization in
the O {\sc i} line at 1302 \AA\, using two-dimensional radiative transfer in a
composite atmosphere constructed using a two-dimensional magneto-hydrodynamical
snapshot in the photosphere and columns of the one-dimensional FALC atmosphere
in the chromosphere. The methods developed by us recently in a series of papers
to solve multi-dimensional polarized radiative transfer have been incorporated
in our new code POLY2D which we use for our analysis. We find that
multi-dimensional radiative transfer including XRD effects is important in
reproducing the amplitude and shape of scattering polarization signals of the O
{\sc i} line at 1302 \AA\,.
