Consider the reaction
Question:

Consider the reaction

$$\mathrm{H}_{2} \mathrm{SO}_{3(\text { aq) }}+\mathrm{Sn}_{(a,)}^{4+}+\mathrm{H}_{2} \mathrm{O}_{(1)} \rightarrow \mathrm{Sn}_{(a q)}^{2+}+\mathrm{HSO}_{4(\text { aq })}^{-}+3 \mathrm{H}_{\text {(aq) }}^{+}$$

Which of the following statements is correct?

1. $\mathrm{H}_{2} \mathrm{SO}_{3}$ is the reducing agent because it undergoes oxidation

2. $\mathrm{H}_{2} \mathrm{SO}_{3}$ is the reducing agent because it undergoes reduction

3. $\mathrm{Sn}^{4+}$ is the reducing agent because it undergoes oxidation

4. $\mathrm{Sn}^{4+}$ is the oxidizing agent because it undergoes oxidation
