$$ \text {Benzyl isocyanide can be obtained from } $$

Choose the correct answer from the options given below :

Consider compounds $\mathrm{A}, \mathrm{B}$ and C with following structural formulae

$$ \begin{aligned} & \mathrm{A}=\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{OH} \\ & \mathrm{~B}=\mathrm{CH}_2=\mathrm{CH}-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CH}_3 \\ & \mathrm{C}=\mathrm{HO}-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CH}(\mathrm{OH})-\mathrm{CH}_3 \end{aligned} $$

For the conversion of B from A , reagent (D) required is $\_\_\_\_$ and structural formula of product $(\mathrm{E})$ obtained when C undergoes same reaction using excess reagent (D) is $\_\_\_\_$ .
