The correct answer is option 2, Quick Lime.

When hydrochloric acid reacts with limestone (option 1), chalk (option 3), and marble (option 4), carbon dioxide is produced as a result. However, when hydrochloric acid reacts with quick lime (option 2), it does not produce carbon dioxide. Quick lime, also known as calcium oxide (CaO), is a strong base. When it reacts with hydrochloric acid (HCl), it forms calcium chloride (CaCl2) and water (H2O), but does not release carbon dioxide.

Limestone, chalk, and marble are all forms of calcium carbonate (CaCO3). In the presence of hydrochloric acid, calcium carbonate undergoes a chemical reaction known as a neutralization reaction. This reaction produces calcium chloride, water, and carbon dioxide gas (CO2). Hence, options 1, 3, and 4 all produce carbon dioxide when reacted with hydrochloric acid.

Therefore, the correct answer is option 2, Quick Lime, as it does not produce carbon dioxide upon reacting with hydrochloric acid.
