Question

Match the dyes given in List-I with their description given in List-II:

List-I (Dyes)	List-II (Description)
(A) Reactive	(I) Applied to fabric as a reduced, water soluble leuco compound
(B) Sulphur	(II) Developed for dyeing acetate fibers
(C) Disperse	(III) Water insoluble dyes
(D) Vat	(IV) Reacts with the fiber molecule by addition or substitution

Choose the correct answer from the options given below:

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

Hint:

Vat dyes always involve the "leuco" reduction and oxidation steps.
Reactive dyes are the only class that chemically reacts to form covalent bonds with the fiber molecules.
