Solution

The correct option is A True
Ammonia reacts with copper (II) oxide to form pure nitrogen.
$2 N H_{3} (g) + 3 C u O (s) \to N_{2} (g) + 3 C u (s) + 3 H_{2} O (g)$
Pure Nitrogen can also be preparing the thermal decomposition of azides, which can be prepared as:
$N_{2} O + 2 N a N H_{2} \to N a N_{3} + N a O H + N H_{3}$
When heated, sodium azide gives
$2 N a N_{3} \to 2 N a + 3 N_{2}$
