Solution

The correct options are
A C is $N H_{4} C l$
C C is recycled into $C a (O H)_{2}$ chamber to from $N H_{3}$
According to process, C is $N H_{4} C l$ . $N H_{4} C l$ is further used to react with $C a (O H)_{2}$ and forms $N H_{3}$ according to reaction. $2 N H_{4} C l + C a (O H)_{2} \to 2 N H_{3} + C a C l_{2} + 2 H_{2} O$
