A
Acids
B
Bases
C
Alkalis
D
None of the above
Explanation: 

Detailed explanation-1: -Non-metal oxides are acidic or neutral in nature. The acidic oxides turn blue litmus red. For example Carbon dioxide.

Detailed explanation-2: -Instead, non-metal oxides are “acidic” (or anhydrides), producing oxo-acids by reacting with water. They are poorly soluble in acidic conditions but dissolve in basic conditions.

Detailed explanation-3: -When non-metallic oxides mix with water, it forms an acid that dissociates to give hydrogen ions, thus they are acidic in nature.

Detailed explanation-4: -Non-metal oxides such as sulphur dioxide contain H+ ions that dissolve in water to form acidic solutions.

Detailed explanation-5: -An acid reacts with a solution of a non-metallic oxide to form salt and water.
