In Ornithine cycle, which of the following wastes are removed from the blood?

In the Ornithine cycle, also known as the urea cycle, the wastes that are removed from the blood are CO2 and urea. The Ornithine cycle is a series of biochemical reactions that occur in the liver and kidneys, and it is responsible for the removal of excess nitrogen from the body. So, the correct answer is option D. Notice that the other options are not correct. Ammonia is a toxic substance that is converted to urea in the Ornithine cycle, but it is not removed from the blood in this cycle. Urine is the waste product that is excreted by the kidneys, but it is not directly related to the Ornithine cycle.
