A diprotic acid is an acid that can donate two protons (H+ ions) per molecule in acidic solutions. Option C, H2SO4, is a diprotic acid as it can donate two protons. Option A, HCl, is a monoprotic acid as it can donate only one proton. Option B does not exist, and option D is a mixture of a monoprotic acid (HPO4-) and a polyprotic acid (H2PO4-), making it incorrect.
