Solution

The correct option is A $B a (N_{3})_{2}$
Very pure nitrogen can be obtained by the thermal decomposition of sodium or barium azide.

$2 N a N_{3} 573 K - -- \to 2 N a + 3 N_{2}$

Azide salt of barium can be obtained in the purest form as well as the decomposition product contains solid Ba as a by-product along with gaseous nitrogen, hence no additional step of separation is required.

$B a (N_{3})_{2} h e a t - - \to B a + 3 N_{2}$

Hence, option $D$ is correct.
