✓

Answer

Correct option: A.
$N_2$ in both cases
a
$\left(\mathrm{NH}_{4}\right)_{2} \mathrm{Cr}_{2} \mathrm{O}_{7} \stackrel{\Delta}{\longrightarrow} \mathrm{N}_{2}+\mathrm{Cr}_{2} \mathrm{O}_{3}+4 \mathrm{H}_{2} \mathrm{O}$

$\mathrm{Ba}\left(\mathrm{N}_{3}\right)_{2} \rightarrow 3 \mathrm{N}_{2}+\mathrm{Ba}$
