Column - I Column - II
\( \begin{array}{ll}\text { (A) } \underline{\mathrm{CuO}} & \text { (p) } 4\end{array} \)
\( \begin{array}{ll}\text { (B) } \mathrm{MnO}_{2} & \text { (q) } 3\end{array} \)
\( \begin{array}{ll}\text { (C) } \mathrm{HAuCCl}_{4} & \text { (r) } 2\end{array} \)
(D) \( \mathrm{Tl}_{2} \mathrm{O} \) (s) 1
(a) \( \mathrm{A}-(\mathrm{r}), \mathrm{B}-(\mathrm{p}), \mathrm{C}-(\mathrm{q}), \mathrm{D}- \) (s)
(b) \( \mathrm{A}-(\mathrm{s}), \mathrm{B}-(\mathrm{r}), \mathrm{C}-(\mathrm{p}), \mathrm{D}-(\mathrm{q}) \)
(c) \( \mathrm{A}-(\mathrm{r}), \mathrm{B}-(\mathrm{s}), \mathrm{C}-(\mathrm{p}), \mathrm{D}-(\mathrm{q}) \)
