Question

Match Column I with Column II and select the right answer:

List-I (Adulteration detection)	List-II (Adulteration detection)
(A) Formalin	(I) Barium chloride
(B) Sodium hypochloride	(II) Detergent
(C) Quaternary Ammonium Compounds	(III) Preservative
(D) Ammonium salts	(IV) Sanitizer

Choose the correct answer from the options given below:

• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (I), (B) - (IV), (C) - (II), (D) - (III)
• (A) - (III), (B) - (IV), (C) - (II), (D) - (I)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

Begin matching with the most definitive chemical associations:
- Formalin is a Preservative (A--III).
- Sodium hypochlorite is a Sanitizer (B--IV).
These two matches quickly narrow down the choices and point directly to option (C).
