Solution

The correct option is B $S O_{4}^{2 -}$
Sulphate ions give white precipitate of lead sulphate when aqueous solution or sodium carbonate extract is neutralised with acetic acid is treated with lead acetate solution
$N a_{2} S O_{4} + (C H_{3} C O O)_{2} P b \to P b S O_{4} White ppt. + C H_{3} C O O N a$

Hence, option (c) is correct.
