Match the columns.
\( \begin{array}{cc}\text { Column-I } & \text { Column-II } \\ \text { (Reactions) } & \text { (Effect of increase in } \\ & \text { pressure) }\end{array} \)
(A) \( \mathrm{H}_{2}(\mathrm{~g})+\mathrm{I}_{2}(\mathrm{~g}) \rightleftharpoons 2 \mathrm{HI}(\mathrm{g})(\mathrm{p}) \) Reaction proceed backward.
(B) \( \mathrm{CO}(\mathrm{g})+\frac{1}{2} \mathrm{O}_{2}(\mathrm{~g}) \)
(q) No effect on \( \rightleftharpoons \mathrm{CO}_{2}(\mathrm{~g}) \quad \) reaction.
(C) \( \mathrm{N}_{2} \mathrm{O}_{4}(\mathrm{~g}) \rightleftharpoons 2 \mathrm{NO}_{2} \) (g) (r) Reaction proceed forward
(a) \( \mathrm{A}-(\mathrm{q}), \mathrm{B}-(\mathrm{r}), \mathrm{C}-(\mathrm{p}) \)
(b) \( \mathrm{A}-(\mathrm{r}), \mathrm{B}-(\mathrm{q}), \mathrm{C}-(\mathrm{p}) \)
(c) \( \mathrm{A}-(\mathrm{p}), \mathrm{B}-(\mathrm{r}), \mathrm{C}-(\mathrm{q}) \)
(d) \( \mathrm{A}-(\mathrm{q}), \mathrm{B}-(\mathrm{p}), \mathrm{C}-(\mathrm{r}) \)
