(D) The decomposition of $H_2O_2$ is represented as: $2H_2O_2(l) ightarrow 2H_2O(l) + O_2(g) + 	ext{Heat}$.$1$. It is an exothermic reaction because heat is released during the process.$2$. It is an example of auto-oxidation (or disproportionation) where the oxygen in $H_2O_2$ (oxidation state $-1$) is both oxidized to $O_2$ $(0)$ and reduced to $H_2O$ $(-2)$.$3$. It is an example of negative catalysis because substances like acetanilide or glycerol act as negative catalysts to slow down its decomposition.Therefore,all the given options are correct.
