Solution

The correct option is B $N a C l, N H_{3}, C O_{2}$
Sodium carbonate can be prepared by the solvay process also known as ammonia - soda process. First sodium chloride reacts with carbon dioxide in presence of ammonia and water to form sodium bicarbonate. Then sodium bicarbonate is converted into sodium carbonate.
