Quizplus · Accepted Answer

The strongest acid is the one with the most stable conjugate base. In this case, the conjugate base of C (HSO4-) is more stable than the conjugate base of any of the other options. This is because the negative charge in HSO4- is spread over a larger surface area with resonance, making it less reactive and more stable.
