The correct match is :

• A. A-1, B-4, C-5, D-2
• B. A-2, B-1, C-4, D-3
• C. A-1, B-4, C-3, D-2
• D. A-5, B-3, C-1, D-4

Answer 1

The correct option is B A-2, B-1, C-4, D-3

Cyanamide process $CaC{O}_3+Ammonia$
Calcium carbonate react with ammonia to produce calcium cyanamide and water. This reaction takes place at a temperature of 700-900°C.

Haber's process - $N_2+3H_2\to 2N{H}_3$
Ostwald's process - Nitric acid is produced from Ostwald's process.
Sulphuric acid is obtained in the Contact process.

The correct match is- A-2, B-1, C-4, D-3
Option B is correct.
