\begin{tabular}{|l|l|c|l|}
\hline \multicolumn{2}{|c|}{ Column-I } & \multicolumn{2}{c|}{ Column-II } \\
\hline A. & Nuclear fusion & p. & \( \begin{array}{l}\text { Converts some matter into } \\
\text { energy }\end{array} \) \\
\hline B. & Nuclear fission & q. & \( \begin{array}{l}\text { Generally possible for nuclei } \\
\text { with low atomic number }\end{array} \) \\
\hline C. & \( \beta \)-decay & r. & \( \begin{array}{l}\text { Generally possible for nuclei } \\
\text { with higher atomic number }\end{array} \) \\
\hline D. & \( \begin{array}{l}\text { Exothermic } \\
\text { nuclear reaction }\end{array} \) & s. & \( \begin{array}{l}\text { Essentially proceeds by weak } \\
\text { nuclear forces }\end{array} \) \\
