Solution

The correct option is B $C O_{2}$ and $C a C O_{3}$

Limewater is an aqueous solution of calcium hydroxide $(C a (O H)_{2})$ .

When carbon dioxide gas is passed through limewater, it turns milky due to the formation of a white precipitate of calcium carbonate.

So, X is carbon dioxide gas and Y is calcium carbonate. The reaction occurs as follows:

$Ca (OH)_{2} (aq) + {CO}_{2} (g) \to {CaCO}_{3} (s) + H_{2} O (l) Calcium Carbon Calcium Water hydroxide dioxide carbonate$
