Which of the following elements are present in Urea?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Carbon, Hydrogen, Oxygen and Nitrogen.
Urea is an organic compound with the chemical formula CO(NH₂)₂. It contains Carbon (C), Hydrogen (H), Oxygen (O), and Nitrogen (N). Urea is widely used as a nitrogen-rich fertilizer in agriculture and is also a major nitrogenous waste product formed in the liver during protein metabolism. Its balanced composition of these four elements makes it an important compound in both biological and industrial processes. Hence, the correct answer includes all four elements—C, H, O, and N.
