Match the entries of column I with appropriate entries of column II. Each entry in column I may have one or more than one correct option from column II. If the correct matches are A-p, \( s \); B-r ; C-p, \( q \); D-s, then the correctly bubbled \( 4 \times 4 \) matrix should be as follows :
\( \begin{array}{lll}\text { (A) Flame colouration } & & \mathrm{Columr} \\ \text { (B) Amphoteric character } & \text { (p) } & \mathrm{Be}(\mathrm{OH}) \\ \text { (C) Soluble in organic solvents } & \text { (q) } & \mathrm{K} \\ \text { (D) Forms superoxide on heating with oxygen } & \text { (r) } & \mathrm{BeCl}_{2} \\ \mathrm{LiCl}\end{array} \)
