5 moles of `AB_(2)` weigh `125xx10^(-3)` kg and 10 moles of `A_(2)B_(2)` weigh `300xx10^(-3)` kg. The molar mass of `A(M_(A))` and molar mass of `B(M_(B)` in kg mol_(-1) are :
A. `M_(A) = 50xx10^(-3) and M_(B) = 25xx10^(-3)`
B. `M_(A) = 25xx10^(-3) and M_(B) = 50xx10^(-3)`
C. `M_(A) = 5xx10^(-3) and M_(B) = 10xx10^(-3)`
D. `M_(A) = 10xx10^(-3) and M_(B) = 5xx10^(-3)`
