Which one of the following reactions involves disproportionation?
(a) \( 2 \mathrm{H}_{2} \mathrm{SO}_{4}+\mathrm{Cu} \rightarrow \mathrm{CuSO}_{4}+2 \mathrm{H}_{2} \mathrm{O}+\mathrm{SO}_{2} \)
(b) \( \mathrm{As}_{2} \mathrm{O}_{3}+3 \mathrm{H}_{2} \mathrm{~S} \rightarrow \mathrm{As}_{2} \mathrm{~S}_{3}+3 \mathrm{H}_{2} \mathrm{O} \)
(c) \( 2 \mathrm{KOH}+\mathrm{Cl}_{2} \rightarrow \mathrm{KCl}+\mathrm{KOCl}+\mathrm{H}_{2} \mathrm{O} \)
(d) \( \mathrm{Ca}_{3} \mathrm{P}_{2}+6 \mathrm{H}_{2} \mathrm{O} \rightarrow 3 \mathrm{Ca}(\mathrm{OH})_{2}+2 \mathrm{PH}_{3} \)
