In a cubic closed packed structure of mixed oxides the lattice is made up of oxide ions, one eighth of tetrahedral voids are occupied by divalent ions `(A^(2+))` while one half of the octahedral voids occupied trivalent ions `(B^(3+))`. What is the formula of the oxide ?
A. `A_(2)BO_(4)`
B. `AB_(2)O_(3)`
C. `A_(2)BO_(3)`
D. `AB_(2)O_(4)`
