(D) When dilute $H_2SO_4$ is added to an inorganic mixture in the cold:$1$. Sulphite $(SO_3^{2-})$ evolves $SO_2$ gas,which has a suffocating,burning sulphur odour.$2$. Acetate $(CH_3COO^-)$ evolves acetic acid,which has a characteristic vinegar-like odour.$3$. Nitrite $(NO_2^-)$ evolves $NO_2$ gas,which is reddish-brown in colour.$4$. Carbonate $(CO_3^{2-})$ evolves $CO_2$ gas,which is colourless and odourless.Therefore,the correct option is $(D)$.

To an inorganic mixture,dilute $H_2SO_4$ is added in the cold; a colourless,odourless gas is evolved. The mixture contains:
