Solution

The correct option is D All of these
$C H_{3} C H_{2} O H [O] \to K_{2} C r_{2} O_{7} / H_{2} S O_{4} C H_{3} C H O [O] \to K_{2} C r_{2} O_{7} / H_{2} S O_{4} C H_{3} C O O H N a O H + C a O \to Δ C H_{4} C l_{2} \to C H_{3} C l a q . K O H \to - K C l C H_{3} O H$ .

Ethanol eventually oxidizes to ethanoic acid with the help of $K_{2} C r_{2} O_{7} / H_{2} S O_{4}$
Decarboxylation of ethanoic acid gives methane, when chlorine is passed through methane forms methyl chloride. In presence of aq. KOH methanol is produced.
Hence, all the reagents are required to convert ethanol to methanol.
Option D is correct.
