(C) The starting material $(P)$ is $2$-oxocyclohexanecarboxylic acid. Heating $(P)$ causes decarboxylation,where the $-COOH$ group is lost as $CO_2$,resulting in the formation of cyclohexanone as intermediate $X$. The subsequent reaction with $Zn-Hg/HCl$ is a Clemmensen reduction,which reduces the carbonyl group $(C=O)$ of cyclohexanone to a methylene group $(CH_2)$. Therefore,the final product $Y$ is cyclohexane.
