The correct options are
A

Bleaching agent


B

Oxidising agent


C

Reducing agent


Sulphur dioxide is used to bleach delicate substances like paper and clothes. In wineries, a mixture of SO2, water, and citric acid is commonly used to clean and sanitize equipment. Hence it can be used as a disinfectant.
Also, it is used as an antichlor to remove free (excess) and combined chlorine to chloride.

In SO2, the central atom exists in +4 oxidation. This means that with the right reagent, it could be oxidized to a higher(say +6) oxidation state. Also, it could be reduced to H2S under the right conditions.
