During the detection of elements by Lassaigne's test, the covalent compounds are converted into ionic compounds by fusion with metallic sodium. The nitrogen, sulphur and halogens present in the organic compound are converted into cyanides, sulphides and halides respectively which are then detected by their usual tests. Which of the following compounds will answer Lassaigne's test for nitrogen ?
