Correct Answer: Urea

Solution : The correct option is Urea .

Urea was the first organic substance synthesised in a laboratory. This was a significant discovery in chemistry since it demonstrated that organic molecules could be synthesised from inorganic starting elements. When ammonium cyanate is heated, it decomposes into urea and ammonia. Urea is a white, odourless substance that is water-soluble. It is the primary nitrogenous waste product generated by animals and is secreted in urine. Urea is also used in fertilisers and other industries.
