Product $(B)$ is

$(I)\,\,CH_3CH_2OH + HCl \xrightarrow{{Anh.\,\,ZnC{l_2}}}$

$(II)\,\,CH_3CH_2OH + HCl \rightarrow$

$(III)\,\,(CH_3)_3COH + HCl \rightarrow$

$(IV)\,\,(CH_3)_2CHOH + HCl \xrightarrow{{Anh.\,\,ZnC{l_2}}}$

$(A)$ $\mathrm{Ni}(\mathrm{CO})_{4}$

$(B)$ $\left[\mathrm{Ni}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right] \mathrm{Cl}_{2}$

$(C)$ $\mathrm{Na}_{2}\left[\mathrm{Ni}(\mathrm{CN})_{4}\right]$

$(D)$ $\mathrm{PdCl}_{2}\left(\mathrm{PPh}_{3}\right)_{2}$

$\begin{array}{l}
C{H_3} - C{H_2} - N{H_2}\\
\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,{\rm{(I)}}
\end{array}$

$\begin{array}{l}
Ph - C{H_2} - N{H_2}\\
\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,{\rm{(II)}}
\end{array}$ 

 $\begin{array}{l}
Ph - N{H_2}\\
\,\,\,\,\,\,\,\,\,{\rm{(III)}}
\end{array}$

Correct order of their basic strength is
