A white precipitate (X) is formed when a mineral of Boron (W) is bolied with `Na_(2)CO_(3)` solution. The precipitate is filtered and the filtered contains two compounds (Y) and (Z). The compound (Y) is removed by crustallization. By passing `CO_(2)` through `(Z)` changes to (Y). The compound (Y) on strong heating givesA. `NaAlO_(2)+Al_(2)O_(3)`B. `NaBO_(2) + B_(2)O_(3)`C. `Na_(2)SO_(4) + H_(3)BO_(3)`D. `CO(BO_(2))_(2)`
