JEE Main 2020 Chemistry question

A crystal is made up of metal ions 'M1' and 'M2' and oxide ions. Oxide ions form a ccp lattice structure. The cation 'M1' occupies 50% of octahedral voids and the cation 'M2' occupies 12.5% of tetrahedral voids of oxide lattice. The oxidation numbers of 'M1' and 'M2' are, respectively :

• (A)+2, +4Correct
• (B)+3, +1
• (C)+1, +3
• (D)+4, +2
