Answer:

Option 1, Cl is reduced and gains electrons

Explanation:

HClO₃  → HClO₂

In HClO₃, chlorine acts with +5 in the oxidation state

In HClO₂,, chlorine acts with +3 in the oxidation state.

The state has been reducted, so the Cl has been reduced. As it was reduced, it means that has won e⁻, in this case 2

Cl⁻⁵  → Cl⁻³  +  2e⁻
