None of the above

Detailed explanation-1: -A salt and water are produced when acids react with metal oxides . Metal oxides are bases, because they neutralise acids.
Detailed explanation-2: -In this reaction, salt and water are formed. Example 1: Calcium is a metal, thus calcium oxide is a metallic oxide which is basic in nature. When an acid (such as hydrochloric acid) reacts with calcium oxide, neutralization reaction takes place and calcium chloride, along with water, is formed.
Detailed explanation-3: -Hence, option (B) is correct, all-metal oxides reacting with water to give salt and acid is not the correct statement.
Detailed explanation-4: -Zinc oxide reacts with hydrochloric acid to give zinc chloride and water. The reaction takes place as follows: ZnO(aq)+2HCl(aq)→ ZnCl2(aq)+H2O(l)
Detailed explanation-5: -acid + metal oxide salt + water. Chloride Salts. hydrochloric acid + sodium oxide sodium chloride + water. 2HCl+ Na2O 2NaCl + H2O. Sulfate Salts. sulfuric acid + calcium oxide calcium sulfate + water. H2SO4+ CaO CaSO4 + H2O. Nitrate Salts. More items
