• C. It cannot be used for all types of crops and soils
• D. The cost of production of urea is cheap.

Answer 1

Answer: (C)

Urea $(N{H}_2-CO-N{H}_2)$ can be used for all types of crops and soil. It is not hazardous hence can be store easily and it is cheap as it can be manufactured from crude nepthalein. After assimilation of urea by plants through the interaction of nitrifying bacteria, it leaves behind only carbon di oxide in the soil.
