Solution

The correct option is B sulphate
A white solid is first heated with dilute $H_{2} S O_{4}$ and then with concentrated $H_{2} S O_{4}$ . No action is observed in either case. The solid contains sulphate.

Solutions containing sulphate ions also react with barium chloride solution, producing a white precipitate of barium sulphate.

For example, $N a_{2} S O_{4} + B a C l_{2}$ $\to 2 N a C l + B a S O_{4} ↓ (w h i t e p p t)$

So, the correct option is $C$
