Solution

The correct options are
A $X$ is $P h C O O H$
B $Z$ is $P h N H_{2}$
D $Y$ is $P h C O N H_{2}$
$P h C O O H X N H_{3} - -- \to Δ P h C O N H_{2} Y B r_{2} / N a O H - ------ \to P h N H_{2} Z C H C l_{3} / K O H - -------- \to P h N C (P h e n y l i s o c y a n i d e)$

Hence option $A, B$ and $D$ are correct.
