Solution

The correct option is D absorbed
In the given reaction, a single compound, i.e., ${Pb(NO}_{3})_{2}$ is breaking down on heating and producing different compounds - $PbO, {NO}_{2}, a n d O_{2}$ . Therefore, this reaction is a decomposition reaction.
Also, the given reaction is an endothermic reaction as heat is absorbed for the reaction to occur.
