Qualitative analysis of organic compound...

Qualitative analysis of organic compounds is performed by Lassaigne's test by fusion with metallic sodium, by which the covalent compounds are converted into ionic compounds. Extra elements like `N,S,P` and halogens are detected by their usual tests.
Q. Which of the following will give blood-red colour in lassaigne's test for nitrogen

A

B

`(NH_(2))_(2)C = O`

C

`C_(6)H_(5)SO_(3)H`

D

`(NH_(4))_(2)SO_(4)`
