The Wavelength \( K_{a} \) X-rays for lead isotopes \( \mathrm{Pb}^{208}, \mathrm{~Pb}^{206} \), and \( \mathrm{Pb}^{204} \) are \( \lambda_{1}, \lambda_{2} \) and \( \lambda_{3} \) respectively. Match the statements of the two columns:
\begin{tabular}{|l|l|l|l|}
\hline \multicolumn{2}{|c|}{ Column 1 } & \multicolumn{2}{c|}{ Column 2 } \\
\hline (A) & \( \lambda_{2} \) & (p) & Equal to \( \left(\lambda_{1} \lambda_{3}\right)^{1 / 2} \) \\
\hline (B) & \( \lambda_{3} \) & (q) & Equal to \( \lambda_{2} \) \\
\hline (C) & \( \lambda_{1} \) & (r) & \( \frac{\left(\lambda_{2}+\lambda_{3}\right)}{2} \) \\
\hline (D) & \( \frac{\lambda_{1}+\lambda_{2}}{2} \) & (s) & \( \frac{\left(\lambda_{3}+\lambda_{1}\right)}{2} \) \\
\hline
\end{tabular}
(1) (A-p, r,s;B-qrs;C-pqs;D-pqrs)
(2) \( (\mathrm{A}-\mathrm{p}, \mathrm{q}, \mathrm{r} ; \mathrm{B}-\mathrm{pqr} ; \mathrm{C}-\mathrm{pqrs} ; \mathrm{D}-\mathrm{qr} s) \)
(3) (A-p, q, r, s;B-pqrs;C-pqrs;D-pqrs)
(4) (A-p, q, r, s;B-qrs;C-prs;D-pqs)
