The correct option is C.
Blue litmus doesn't show a colour change when a dry litmus is exposed to sulphur dioxide because sulphur dioxide is a weak acid.
- In presence of strong acid blue litmus change its colour to red.
- But sulphur dioxide is a weak acid so, it can't change the color of blue litmus to red.
