Prashant Kotian · Accepted Answer

Correct answer: B. Step 1: Chlorine trioxide (ClO3) contains chlorine in the +6 oxidation state. Upon hydrolysis, it disproportionates to form chloric acid (HClO3) and perchloric acid (HClO4). Step 2: Both chloric acid and perchloric acid are oxyacids containing the "-ic" suffix. Step 3: Since the chlorine-containing products are oxyacids with an "-ic" suffix, the correct option is (a).
