The two equilibrium `AB hArr A^(+) + B^(-) and AB+B^(-)hArrAB_(2)^(-)` are simultaneously maintained in a solutio with equilibrium constant `K_(1) and K_(2)` respectively. The ratio of `[A^(+)] ` to `[AB_(2)^(-)]` in the solution is
A. directly proportional to the concentration of `B^(-)`
B. inversely proportional to the concentration of `B^(-)`
C. directly proporitonal to the squar eof the concentration of `B^(-)`
D. Inversely proportional to the square of the concentration of `B^(-)`.
