Match the reagents (List-I) with the products (List-II) obtained from phenol and select the correct option.

List-I (Reagents) (A) (i) NaOH, (ii) CO₂, (iii) H⁺ (B) (i) Aqueous NaOH + CHCl₃, (ii) H⁺ (C) Zn dust, \Delta (D) Na₂Cr₂O₇, H₂SO₄

List-II (Products) (I) Benzoquinone (II) Benzene (III) Salicylaldehyde (IV) Salicylic acid

The matching is based on the specific chemical reactions of phenol:

1. Kolbe's Reaction (A): Phenol reacts with NaOH to form phenoxide, which then undergoes electrophilic substitution with weak electrophile $CO_2$ followed by acidification to form Salicylic acid (2-Hydroxybenzoic acid). [Match: A-IV]
2. Reimer-Tiemann Reaction (B): Treatment of phenol with chloroform ($CHCl_3$) in the presence of aqueous NaOH introduces an aldehyde group at the ortho position, forming Salicylaldehyde (2-Hydroxybenzaldehyde). [Match: B-III]
3. Reaction with Zinc dust (C): Phenol is reduced to Benzene when heated with zinc dust. [Match: C-II]
4. Oxidation (D): Oxidation of phenol with chromic acid ($Na_2Cr_2O_7 + H_2SO_4$) produces a conjugated diketone known as Benzoquinone. [Match: D-I]
