Solution

The correct option is B
II & III

The given reaction is a type of decomposition reaction as the single compound $(P b (N O_{3})_{2})$ when heated breaks down to form other different compounds $(P b O, N O_{2}, O_{2})$ and as heat is provided for the reaction to happen, it is also an endothermic reaction.
So both II - Decomposition & III - Endothermic are correct options.
