(D) The hydration of alkynes in the presence of $HgSO_4$ and $H_2SO_4$ is known as the $Kucherov$ reaction,which produces ketones. $1.$ Hydration of $But-1-yne$: $CH_3-CH_2-C \equiv CH + H_2O$ $\xrightarrow[H_2SO_4]{HgSO_4} [CH_3-CH_2-C(OH)=CH_2]$ $\rightarrow CH_3-CH_2-CO-CH_3$ (Butan$-2-$one). $2.$ Hydration of $But-2-yne$: $CH_3-C \equiv C-CH_3 + H_2O$ $\xrightarrow[H_2SO_4]{HgSO_4} [CH_3-C(OH)=CH-CH_3]$ $\rightarrow CH_3-CO-CH_2-CH_3$ (Butan$-2-$one). Since both reactants $(A)$ and $(B)$ yield the same product,the correct option is $(D)$.

In the reaction $x + H_2O \xrightarrow[H_2SO_4]{HgSO_4} CH_3-CO-CH_2-CH_3$,the reactant $x$ is:
