Solution

The correct option is B Sodium ethanoate and gas evolved is carbon dioxide.
$C H_{3} C O O H + N a H C O_{3} \to C H_{3} C O O N a + H_{2} O + C O_{2}$ .

The gas evolved during the reaction is passed through a delivery tube into the test tube containing lime water.

The lime water solutions turns milky due to the formation of calcium carbonate, a characteristic property of $C O_{2}$ gas.

X is sodium ethanoate. Gas evolved is carbon dioxide.

Option B is correct.
