• A. I-c, II-a, III-b, IV-d
• B. I-a, II-d, III-b, IV-c
• C. I-d, II-a, III-c, IV-b
• D. I-c, II-b, III-a, IV-d

Answer 1

The correct option is D I-c, II-b, III-a, IV-d

1. Sodium bicarbonate is a basic salt.
   
2. Alum is hydrated potassium aluminium sulphate. Hence, its a mixed salt ($KAl{\left({SO}_4\right)}_2\cdot 12H_{2}O$).
3. Bleaching powder is calcium-oxychloride which is double salt.
   
4. Sodium chloride is normal salt.
