X, Y and Z are three aqueous solutions. Equal volumes of two solutions at a time are combined and the results are observed. When X is mixed with Y, no reaction occurs. When X is mixed with Z, a reaction happens immediately. When Z is mixed with Y, no reaction occurs. What are X, Y and Z?
- AX: $\text{Br}_2(aq)$, Y: $\text{I}_2(aq)$, Z: $\text{HBr}(aq)$
- BX: $\text{Cl}_2(aq)$, Y: $\text{I}_2(aq)$, Z: $\text{HBr}(aq)$
- CX: $\text{HCl}(aq)$, Y: $\text{HI}(aq)$, Z: $\text{Br}_2(aq)$
- DX: $\text{HCl}(aq)$, Y: $\text{Br}_2(aq)$, Z: $\text{HBr}(aq)$
