    Answer : Option B

    Explanation :

    Urea fertilisers provides maximum amount of nitrogen. Urea (46-0-0) is a dry nitrogen material produced by reacting ammonia with carbon dioxide. Of the commonly used dry fertilizers, urea contains the highest percentage of nitrogen and is rapidly replacing ammonium nitrate. When surface applied, urea is the most readily volatilized of the dry nitrogen materials.
