Element $\mathrm{B}$ forms ccp structure and $\mathrm{A}$ occupies half of the octahedral voids, while oxygen atoms occupy all the tetrahedral voids. The structure of bimetallic oxide is:

• A

  ${\mathrm{A}}_2\mathrm{B}{\mathrm{O}}_4$
• Correct answer
  B

  $\mathrm{A}{\mathrm{B}}_2{\mathrm{O}}_4$
• C

  ${\mathrm{ }\mathrm{A}}_2{\mathrm{B}}_2\mathrm{O}$
• D

  ${\mathrm{ }\mathrm{A}}_4{\mathrm{B}}_2\mathrm{O}$

Hence, the correct answer is option: 'B'.
