Solution

The correct option is A $N a C l, N H_{3}, C a C O_{3}$
the raw materials used in Solvay's process are:
$N a C l, N H_{3}, a n d C a C O_{3}$ .
The following reaction in solvay's process took place:
$C a C O_{3} \to C a O + C O_{2}$
$2 N H_{3} + C O_{2} + H_{2} O \to {(N H_{4})}_{2} C O_{3}$
${(N H_{4})}_{2} C O_{3} + C O_{2} + H_{2} O \to 2 N H_{4} H C O_{3}$
$N H_{4} H C O_{3} + N a C l \to N a H C O_{3} + N H_{4} C l$
$2 N a H C O_{3} \to N a_{2} C O_{3} + H_{2} O + C O_{2}$
