The correct Answer is:
2
Nitrogen may be obtained in the elementary form by heating urea with nitrous acid.
`underset("Urea")(H_(2)NCONH_(2))+2NHO_(2)rarr2N_(2)+CO_(2)+3H_(2)O`
Nitrous acid is unstable and is always prepared in situ by the action of dilute sulphuric acid on sodium or potassium nitrite.
