a) SO2 acidic
b) Na2O basic
c) CO2 acidic
d) CaO basic
e) no correct answer -wrong
Arrhenius bases produce OH- ions by definition when dissolved in water. A Bronsted - Lowry base can produce OH- ions, but only has to produce a proton accepting group by definition. A Lewis base is defined as an electron donating group, which hydroxide ion is. So, basic compounds do produce OH- ions when dissolved in water, but not in all cases.
Calcium carbonate (CaCO3) is a basic substance because it is an alkaline compound. When dissolved in water, it will produce a slightly basic solution.
When a non-metal oxide, such as sulfur dioxide, is dissolved in water, it forms an acidic solution. This is because non-metal oxides react with water to produce acids.
Aqueous solutions of calcium oxide (CaO) are basic because they produce hydroxide ions when dissolved in water. Calcium oxide reacts with water to form calcium hydroxide, which dissociates to release hydroxide ions, increasing the pH of the solution and making it basic.
Barium nitrite is considered basic because it can form hydroxide ions in solution. When dissolved in water, it will produce barium hydroxide, which can partially dissociate to release OH- ions, making the solution basic.

Ammonia gas when dissolved in water produce Ammonium hydroxide so its solution is basic.
Chlorine gas dissolves in water to form hydrochloric acid (HCl), not a basic solution. When dissolved in water, chlorine gas reacts with water to produce hydrochloric acid and hypochlorous acid, which is a weak acid. This reaction contributes to the acidic nature of the solution, rather than making it basic.
Most metal hydroxides and oxides e.g. K2O and KOH

Yes, dissolved soap is a basic solution.
When bases dissolve in water, they usually form alkaline solution. An alkaline solution has a pH that is more than seven.
solute is the substance being dissolved, solvent is the substance doing the dissolving. A solution is a mixture, not a compound. There is no exact formula for a solution, there can be a small amount dissolved (called a dilute solution) or a large amount dissolved (called a concentrated solution). Sugar in water is a solution, sugar is the solute, water is the solvent.
Calcium cyanide is basic. It forms hydroxide ions when dissolved in water, making the solution basic.
