The reaction of $\displaystyle \mathrm{H}_3 \mathrm{~N}_3 \mathrm{~B}_3 \mathrm{Cl}_3(\mathrm{~A})$ with $\displaystyle \mathrm{LiBH}_4$ in tetrahydrofuran gives inorganic benzene (B). Further, the reaction of (A) with (C) leads to $\displaystyle \mathrm{H}_3 \mathrm{~N}_3 \mathrm{~B}_3(\mathrm{Me})_3$. Compounds (B) and (C) respectively, are :
