The correct answer among the choices given is option A. Hydrochloric acid is a much stronger acid than sulfuric acid given that the concentration both is equal. This can be proved by the pKa of these acids. Hydrochloric acid has a pKa of -6 while the pKa of sulfuric acid is -3. The lower the value of the pKa, the stronger the acidity of the substance.
