Solution

The correct option is A True
It acts as both oxidant and reductant. Treatment of basic solutions with sulphur dioxide affords sulphite salts. Sulphur in the +4 oxidation state sulphur dioxide is a reducing agent.
$2 N a O H + {S O}_{2} \to {{N a}_{2} S O}_{3} + H_{2} O$
Sulphur dioxide is oxidized by halogens to give the sulphuryl halides such as sulphuryl chloride. Sulphur dioxide acts as oxidising agent.
${S O}_{2} + {C l}_{2} \to {S O}_{2} {C l}_{2}$
