Which of the following compounds represents acrylonitrile?

Match List-$I$ with List-$II$ and then select the correct answer from the codes given below the lists.

List-$I$	List-$II$
$A.$ Butane $\to$ Isobutane	$(a).$ Cracking
$B.$ Butane $\to$ Lower hydrocarbons	$(b).$ Isomerisation
$C.$ $n-$Heptane $\to$ Toluene	$(c).$ Reed reaction
$D.$ Propane $\to CH_3CH_2CH_2SO_2Cl$	$(d).$ Aromatization

Compound $(X)$ will be:
Compound $(X) \xrightarrow[Pt]{5H_2} \text{Saturated compound}$
Compound $(X) \xrightarrow{AgNO_3} \text{Precipitate}$
Compound $(X) \xrightarrow[Me_2S]{O_3} OHC-CH_2-CH_2-CO-CHO + HOOC-CHO + HCOOH + OHC-CHO$
