(B) The reaction of $BCl_3$ with $H_2$ in the presence of a $Cu-Al$ catalyst at $450^{\circ}C$ produces diborane $(B_2H_6)$ as product $X$: $2BCl_3 + 6H_2 \xrightarrow{Cu-Al, 450^{\circ}C} B_2H_6 + 6HCl$ Diborane $(B_2H_6)$ undergoes methylation with $CH_3Cl$ to form tetramethyldiborane, which is $Z$: $B_2H_6 + 4CH_3Cl \rightarrow (CH_3)_4B_2H_2 + 4HCl$ Thus, $Z$ is $(CH_3)_4B_2H_2$.
