As we have learnt, 

Heating of \mathrm{PbNO_3} produces \mathrm{NO_2} apart from \mathrm{PbO} and \mathrm{O_2} as given below

\mathrm{Pb}\left(\mathrm{NO}_{3}\right)_{2} \stackrel{673 \mathrm{~K}}{\longrightarrow} 4 \mathrm{\underset{(A)}{NO_{2}}}+2 \mathrm{PbO}+\mathrm{O}_{2}

So, Option (1) is correct
