Options

A. `{:(Cr(OH)_(3),ClO^(-),CrO_(4)^(2-),Cl^(-)),(" 2"," 3"," 3","3"):}`
B. `{:(Cr(OH)_(3),ClO^(-),CrO_(4)^(2-),Cl^(-)),(" 2"," 4"," 3","2"):}`
C. `{:(Cr(OH)_(3),ClO^(-),CrO_(4)^(2-),Cl^(-)),(" 2"," 4"," 4","2"):}`
D. `{:(Cr(OH)_(3),ClO^(-),CrO_(4)^(2-),Cl^(-)),(" 2"," 3"," 2","3"):}`

Answer

D
