Solution

The correct option is C ${C r}_{2} O_{3}$
$({N H}_{4})_{2} {C r}_{2} O_{7} Δ - \to {C r}_{2} O_{3} + N_{2} + 4 H_{2} O$

The green-coloured $C r_{2} O_{3}$ powder is blown in the air by the large volume of $N_{2}$ and water vapour produced and settles like dust from the volcano.

Hence, the correct option is $B$
