MATCH THE COLUMN
If \( \mathrm{a}= \) absorptance, \( \mathrm{r}= \) reflectance and \( \mathrm{t}= \) transmittance then match the nature of different bodies.
\begin{tabular}{|l|l|l|l|}
\hline \multicolumn{2}{|c|}{ Column-I } & \multicolumn{2}{c|}{ Column-II } \\
\hline A. & If \( \mathrm{a}=\mathrm{t}=0 \) and \( \mathrm{r}=1 \) & p. & Body is perfect absorber \\
\hline B. & If \( \mathrm{r}=\mathrm{t}=0 \) and \( \mathrm{a}=1 \) & q. & Body is perfect reflector \\
\hline C. & \( \mathrm{a}=\mathrm{r}=0 \) and \( \mathrm{t}=1 \) & r. & \( \begin{array}{l}\text { Body is perfect } \\
\text { transmitter }\end{array} \) \\
\hline
\end{tabular}
(1) A-(q); B-(p); C-(r)
(2) A-(p); B-(q); C-(r)
(3) A-(r); B-(p); C-(q)
(4) None of these
