In a triangle \( A B C, A D \) is perpendicular to \( B C \) and \( D E \) is perpendicular to \( A B \).
\begin{tabular}{|l|l|l|l|}
\hline \multicolumn{2}{|c|}{ Column-I } & \multicolumn{2}{c|}{ Column-II } \\
\hline A. & Area of \( \triangle A D B \) & p. & \( \left(b^{2} / 4\right) \sin 2 C \) \\
\hline B. & Area of \( \triangle A D C \) & q. & \( \left(c^{2} / 4\right) \cos ^{2} B \sin 2 B \) \\
\hline C. & Area of \( \triangle A D E \) & r. & \( \left(c^{2} / 4\right) \sin 2 B \) \\
\hline D. & Area of \( \triangle B D E \) & s. & \( \left(c^{2} / 4\right) \sin ^{2} B \sin 2 B \) \\
\hline
\end{tabular}
