A bird is flying at the height of \( 12 \mathrm{~cm} \) from the surface of a lake and a fish is swimming at a depth of \( 24 \mathrm{~cm} \) from the surface. (Take is \( \mu=4 / 3 \) )
\begin{tabular}{|l|l|c|l|}
\hline & \multicolumn{1}{|c|}{ Column-I } & & \multicolumn{1}{|c|}{ Column-II } \\
\hline A. & \( \begin{array}{l}\text { Distance of fish from the } \\
\text { surface as seen by bird }\end{array} \) & p. & \( 16 \mathrm{~cm} \) \\
\hline B. & \( \begin{array}{l}\text { Distance of bird from the } \\
\text { surface as seen by fish }\end{array} \) & q. & \( 40 \mathrm{~cm} \) \\
\hline C. & \( \begin{array}{l}\text { Distance between fish } \\
\text { and bird as seen by bird }\end{array} \) & r. & \( 18 \mathrm{~cm} \) \\
\hline D & \( \begin{array}{l}\text { Distance between fish } \\
\text { and bird as seen by fish }\end{array} \) & s. & \( 30 \mathrm{~cm} \) \\
