(C) The Kolbe electrolysis or Kolbe reaction is an organic reaction named after Hermann Kolbe. The Kolbe reaction is formally a decarboxylative dimerisation of two carboxylic acids (or carboxylate ions). The overall general reaction is: $2RCOO^- \longrightarrow R-R + 2CO_2 + 2e^-$. After electrolysis,an alkane (hydrocarbon) is formed at the anode along with the release of carbon dioxide $(CO_2)$. When potassium acetate $(CH_3COO^- K^+)$ is used in electrolysis,carbon dioxide is released along with ethane $(H_3C-CH_3)$. $CH_3COO^- \longrightarrow CH_3^{\bullet} + CO_2 + e^-$ $2CH_3^{\bullet} \longrightarrow C_2H_6$ Thus,both hydrocarbons and $CO_2$ are released at the anode. Option $C$ is the correct answer.

Column-$I$ (Acid)	Column-$II$ (Formula) and Column-$III$ ($IUPAC$ Name)
$(A)$ Adipic acid	$(ii)$ $HOOC(CH_2)_4COOH$ ; $(y)$ Hexanedioic acid
$(B)$ Carballylic acid	$(iii)$ $HOOC-CH_2-CH(COOH)-CH_2-COOH$ ; $(n)$ Propane-$1,2,3$-tricarboxylic acid
$(C)$ Phthalic acid	$(i)$ $1,2-C_6H_4(COOH)_2$ ; $(x)$ Benzene-$1,2$-dicarboxylic acid
$(D)$ Glutaric acid	$(iv)$ $HOOC(CH_2)_3COOH$ ; $(m)$ Pentanedioic acid
