Solution
The correct option is D Urea
Nitrogenous wastes include ammonia, uric acid, and urea. The amino acids and nucleic acids contain nitrogen. During the metabolism of amino acids, the nitrogen-containing amino group is removed (in a process known as deamination) and converted to ammonia. Urea, the principal nitrogenous waste product of amphibians and mammals, is synthesised in the liver from ammonia and carbon dioxide by a sequence of reactions, known as the urea cycle.
