Explanation
The liver is responsible for the production of urea through a process known as the urea cycle or the ornithine cycle. This process involves converting toxic ammonia, which is a byproduct of protein metabolism, into urea. Once produced by the liver, urea is released into the bloodstream and eventually filtered out by the kidneys to be excreted in urine.
Regarding the other options, lipase is primarily produced by the pancreas and small intestine, mucus is secreted by various mucous membranes throughout the body, and hydrochloric acid is produced by the parietal cells in the stomach. Therefore, urea is the correct answer as it is the only substance in the list synthesized by the liver.
