The correct answer is A. CaCO3

Bubbling carbon (IV) oxide (CO<sub>2</sub>) into calcium hydroxide solution results in the formation of CaCO<sub>3</sub> (Calcium Carbonate)

This is a common demonstration of a chemical reaction where a gas (carbon dioxide) reacts with a solution (calcium hydroxide) to form a precipitate (calcium carbonate) and water.

The reaction can be represented as follows:

Ca(OH)<sub>2</sub> (aq) + CO<sub>2</sub> (g) → CaCO<sub>3</sub> (s) + H<sub>2</sub>O (l)
