Solution

The correct option is C acidic
The reaction of sulphur and oxygen gives sulphur dioxide gas. The reaction involved is:

$S (s) + O_{2} (g) \to {SO}_{2} (g)$

When sulphur dioxide is dissolved in water, sulphurous acid is formed. It turns blue litmus paper red. The reaction involved is:

${SO}_{2} (g) + H_{2} O (l) \to H_{2} {SO}_{3} (l)$

Hence, the oxide formed is acidic in nature.
