C Correct answer
Explanation

Arginase is the final enzyme in the urea cycle (ornithine cycle) that converts arginine to urea and ornithine in the liver. This is the fifth and final step of urea production. Urease breaks down urea (opposite direction), and uricase acts on uric acid, not urea production.
