Match List-I with List-II

List-I (Adulterant in milk)	List-II (Reagent)
(A) Sugar	(I) Barfoed's Reagent
(B) Ammonium Salts	(II) Silver nitrate
(C) Glucose	(III) Seliwanoff's Reagent
(D) Salt	(IV) Nessler's Reagent

Choose the correct answer from the options given below

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

Hint:

Keep this key reagent guide in mind for milk adulterants:
- Sucrose/Sugar \(\rightarrow\) Seliwanoff's reagent (Red color).
- Ammonium salts \(\rightarrow\) Nessler's reagent (Yellow-brown precipitate).
- Glucose \(\rightarrow\) Barfoed's reagent (Rapid red precipitate).
- Added salt \(\rightarrow\) Silver nitrate (Chloride titration).
