$ `ZnCO_(3)` will not give any gas when treated with conc. `H_2SO_(4)`

1.	$ `ZnCO_(3)` will not give any gas when treated with conc. `H_2SO_(4)` ! `CO_(3)^(2-)` can only be detected in dil. Acid testA. Both A and R are true and R is the correct explanation of AB. Both A and R are true but R is not a correct explanation of AC. A is true but R is falseD. Both A and are false
Answer» Assertion: `ZnCO_(3)` will react with conc. `H_(2)SO_(4)` to give `CO_(2)` Reason: Radicals of dil. Acid test are decomposed by conc. `H_(2)SO_(4)` in cold.
