The correct answer is A. Urea.
Urea was the first organic compound to be synthesized in the laboratory. In 1828, Friedrich Wöhler heated ammonium cyanate and obtained urea, a substance found in urine. This discovery
showed that organic compounds could be synthesized from inorganic compounds, and it was a major breakthrough in chemistry.Uric acid is a waste product produced by the body when it breaks down purines. It is found in urine and blood. Uric acid can build up in the body and cause gout, a type of arthritis.
Lactic acid is a type of acid that is produced when the body breaks down glucose for energy. It is also found in milk and sour cream. Lactic acid can build up in the muscles and cause muscle cramps.
Glucose is a type of sugar that is found in the blood. It is the body’s main source of energy. Glucose is also found in fruits, vegetables, and grains.
