In a close packed structure of mixed oxides, the lattice is composed of oxide ions, one eighth of tetrahedral voids are occupied by divalent cations while one half of octahedral voids are occupied by trivalent cations. What is the formula of the oxide?
(a) \( \mathrm{AB}_{2} \mathrm{O}_{4} \)
(b) \( \mathrm{AB}_{4} \mathrm{O}_{4} \)
(c) \( \mathrm{ABO}_{2} \)
(d) \( \mathrm{ABO}_{3} \)
