C Correct answer
Explanation

In the liver's urea cycle (ornithine cycle), toxic ammonia (NH₃) combines with carbon dioxide (CO₂) to form urea, which is then excreted by kidneys. This is the primary pathway for nitrogen waste removal in humans. HCl is stomach acid, chromium is a mineral, and ammonium dioxide is not a biological product.
