\begin{tabular}{|l|l|l|l|}
\hline \multicolumn{2}{|c|}{ Column-I } & \multicolumn{2}{c|}{ Column-II } \\
\hline A. & \( \begin{array}{l}\text { Work done by normal } \\
\text { reaction }\end{array} \) & p. & Positive \\
\hline B. & Work done by gravity & q. & Negative \\
\hline C. & Work done by friction & r. & zero \\
\hline D. & Work done by tension & s. & Cant say anything \\
\hline
\end{tabular}
(a) A-(q); B-(r); C-(q); D-(r)
(b) A-(p); B-(q); C-(r); D-(p)
(c) A-(r); B-(p); C-(s); D-(q)
(d) A-(q); B-(r); C-(p); D-(r)
