In a cubic close packed structure of mixed oxides, the lattice is made up of oxide ions, one eighth of tetrahedral voids are occupied by divalent \( \left(\mathrm{X}^{2+}\right) \) ions, while one-half of the octahedral voids are occupied by trivalent ions \( \left(\mathrm{Y}^{3+}\right) \), then the formula of the oxide is
(1) \( \mathrm{XY}_{2} \mathrm{O}_{4} \)
(2) \( \mathrm{X}_{2} \mathrm{YO}_{4} \)
(3) \( X_{4} Y_{5} O_{10} \)
(4) \( X_{5} Y_{4} O_{10} \)
