\(B(OH)_3 \)and \(NH_3\)
\(B_2H_6\) and \(NH_3\)
\(B_2H_6 \)and \(HN_3\)
\(NH_3\) and \(B_2O_3\)
\(3B_2H_6 + 6NH_3 → 2B_3N_3H_6\)
(Borazine)
So, the correct option is (B): \(B_2H_6\) and \(NH_3\).
Method used for separation of mixture of products (B and C) obtained in the following reaction is: 
Let \( \alpha = \dfrac{-1 + i\sqrt{3}}{2} \) and \( \beta = \dfrac{-1 - i\sqrt{3}}{2} \), where \( i = \sqrt{-1} \). If
\[ (7 - 7\alpha + 9\beta)^{20} + (9 + 7\alpha - 7\beta)^{20} + (-7 + 9\alpha + 7\beta)^{20} + (14 + 7\alpha + 7\beta)^{20} = m^{10}, \] then the value of \( m \) is ___________.
