Solution

The correct option is D paramagnetic
$3PbS + {Conc. 8HNO}_{3} ⟶ {3Pb(NO}_{3})_{2} ↓ + 3S ↓ + 2NO (g) + 4 H_{2} O$

The gas formed is nitric oxide, i.e., NO. It has an odd electron in it so it is paramagnetic in nature..

$\begin{matrix} NO (g) is & \Rightarrow Paramagnetic \Rightarrow Colourless \end{matrix}$
