This section contains 4 questions. Questions 68 and 69 have three statements ( \( \mathrm{A}, \mathrm{B} \) and \( \mathrm{C} \) ) given in Column I and four statements ( \( p, q, r \) and \( s \) ) in Column II and questions 70 and 71 have four statements (A, B, C and D) given in Column I and five statements (p, q, r, \( s \) and t) in Column II. Any given statement in Column I can have correct matching with one or more statement(s) given in Column II.
\begin{tabular}{l|l|l|l}
\hline \multicolumn{1}{c|}{ Column I } & \multicolumn{2}{c}{ Column II } \\
\hline (A) & If \( \left|z-\frac{1}{z}\right|=2 \) and if greatest and least values of \( |z| \) are \( G \) and \( L \) respectively, then \( G-L \), is & (p) & natural number \\
\hline (B) & If \( \left|z+\frac{2}{z}\right|=4 \) and if greatest and least values of \( |z| \) are \( G \) and \( L \) respectively, then \( G-L \), is & (q) & prime number \\
\hline (C) & If \( \left|z-\frac{3}{z}\right|=6 \) and if greatest and least values of \( |z| \) are \( G \) and \( L \) respectively, then \( G-L \), is & (r) & composite number \\
\hline & (s) & perfect number \\
\hline
\end{tabular}
