\(2 \mathrm{H}_{2} \mathrm{~S}_{(\mathrm{g})}+\mathrm{SO}_{2(\mathrm{~g})}
ightarrow 3 \mathrm{~S}_{(\mathrm{g})}+\) \(2 \mathrm{H}_{2} \mathrm{O}_{(1)}\).

The above reaction is ____________

A. a redox reaction in which \(\mathrm{H}_{2} \mathrm{~S}\) is the oxidant and \(\mathrm{SO}_{2}\) is the reductant
B. a redox reaction in which \(\mathrm{SO}_{2}\) is the oxidant and \(\mathrm{H}_{2} \mathrm{~S}\) is the reductant  
C. not a redox reaction because there is no oxidant in the reaction equation
D. not a redox reaction because there is no reductant in the reaction equation
