Oxidation states of A,B and C are +2,+5 and -2
Let us substitute these oxidation state each of the compound given
All the compounds given are neutral the algebric sum of oxidations number must be zero
Option :1
A₂(BC)₂
2(+2) + [+5 -2]2
4+6 = 10
Option:2
A₂(BC₄)₃
2(+2) + [+5+4(-2)]3
4-9 = -5
Option:3
A₃(BC₄)₂
3(+3)+[+5+4(-2)]2
6 - 6 = 0
Option:4
ABC
+2 +5 -2
= +5
The compound A₃(BC₄)₂
