An organic compound $X$ $(C_7H_7Cl)$ when reacted with $KCN$ in $C_2H_5OH$ gives a major product $Y$. $Z$ is formed when $Y$ is reduced with $LiAlH_4$. What are $Y$ and $Z$?

  • A
    $Y$ = Benzyl isocyanide,$Z$ = $N$-methylbenzylamine
  • B
    $Y$ = Benzyl cyanide,$Z$ = Phenylethylamine
  • C
    $Y$ = p-Methylbenzonitrile,$Z$ = p-Methylbenzylamine
  • D
    $Y$ = p-Methylphenyl isocyanide,$Z$ = $N$-methyl-p-toluidine
