Solution

The correct option is A $P b (N O_{3})_{2}$
$P b {(N O_{3})}_{2}$ on heating it gives a brown coloured gas $N O_{2}$ and $O_{2}$ gas.

Equation is as follows:

$2 P b {(N O_{3})}_{2} 673 K \to 4 N O_{2} + 2 P b O + O_{2}$

Here it is a mixture of two gas i.e. nitrogen-dioxide and oxygen gas.

Hence option C is the correct answer
