Answer (2)

The only pure substance among the options is carbon dioxide (option D), as it has a consistent composition of carbon and oxygen. Soda, gasoline, and salt water are all mixtures and thus not pure substances. A pure substance is defined as having a uniform and definite composition without variations.
