Answer:The correct answer is option b.
Explanation:
Acid a are those compound which gives hydronium ions in their aqueous solution.
[tex]HA+H_2O\rightarrow A^-+H_3O^+[/tex]
[tex]H_2SO_4+H_2O\rightarrow SO_{4}^{2-}+2H^+[/tex]
Sulfuric acid in its aqueous solution gives sulfate ions and hydronium ions.
Hence, the correct answer is option b.
