    In a cubic packed structure of mixed oxides, the lattice is made up of oxide ions, one fifth of tetrahedral voids are occupied by divalent \[({{X}^{2+}})\]ions. while one half of the octahedral voids are occupied by trivalent ions \[({{Y}^{3+}})\], then the formula of the oxide is

    A)  \[X{{Y}_{2}}{{O}_{4}}\]       

    B)  \[{{X}_{2}}Y{{O}_{4}}\]

    C)  \[{{X}_{4}}{{Y}_{5}}{{O}_{10}}\]
