Urea is

🔑Key Points:
-Urea is a nitrogen-containing organic compound.
-Urea or carbamide is an organic compound with chemical formula CO(NH2)2.
-The molecule has two -NH2 groups joined by a carbonyl (C=O) functional group.
-Urea is the only controlled fertilizer, which is sold at the statutory notified uniform sale price.
-Dissolved in water, it is neither acidic nor alkaline. 
-It is a colourless, odourless solid, highly soluble in water, and practically non-toxic.
-Hence, option 1 is correct. 

🔴Additional Information:
-Urea has important uses as a fertilizer and feeds supplement, as well as a starting material for the manufacture of plastics and drugs.
-It is a colourless, crystalline substance that melts at 132.7° C (271° F) and decomposes before boiling. 
-Its nitrogen content is high and is readily converted to ammonia in the soil, urea is one of the most concentrated nitrogenous fertilizers. 
-Urea nitrogen is in nonprotein form, it can be utilized by ruminant animals (cattle, sheep), and a significant part of these animals’ protein requirements can be met in this way. 
-In the course of the breakdown of proteins, amino groups (NH2) are removed from the amino acids that partly comprise proteins.
-These amino groups are converted to ammonia (NH3), which is toxic to the body and thus must be converted to urea by the liver.
-The urea then passes to the kidneys and is eventually excreted in the urine.
