Explanation:

The correct answer is Option (1) → (A)-(IV), (B)-(II), (C)-(I), (D)-(III)

List-I (IUPAC name)

List-II (Common name)

(A) 2,4,6-Trinitrophenol

(IV) Picric caid

(B) Benzene-1,4-diol

(II) Quinol

(C) Benzene-1,3-diol

(I) Resorcinol

(D) 2-methyl phenol

(III) o-Cresol

(A) 2,4,6-Trinitrophenol (IV): This is a highly nitrated phenol where three nitro groups ($-NO_2$) are attached at the 2, 4, and 6 positions. It is famously known as Picric acid, a strong acid and explosive.

(B) Benzene-1,4-diol (II): This compound has two hydroxyl groups ($-OH$) at the para positions (1 and 4) of the benzene ring. Its common names are Quinol or Hydroquinone.

(C) Benzene-1,3-diol (I): This isomer has two hydroxyl groups at the meta positions (1 and 3). It is commonly known as Resorcinol.

(D) 2-Methylphenol (III): This compound consists of a methyl group ($-CH_3$) attached to the ortho position relative to the hydroxyl group. It is commonly called o-Cresol.
