• D. None of the above

Answer 1

The correct option is C Sulfites produce $S{O}_2$ gas, which smells of burning sulfur, when treated with dilute acetic acid

$Sulfites$ do not produce $S{O}_2$ gas when they are treated with dilute acetic acid.

Although, $S{O}_2$ gas does smell like burning sulfur.
