Your answer:

Correct:
B
Explanation
The liver’s role in nitrogen metabolism includes converting toxic ammonia (from amino-acid breakdown) into the less toxic compound urea via the urea cycle; urea is then exported for renal excretion [1]. By contrast, hydrochloric acid and mucus are secretions of the stomach’s gastric glands — parietal cells produce HCl and other gastric cells secrete mucus to protect the mucosa — so these are not liver functions [2]. Lipase is primarily produced by the pancreas (and also by some brush-border and gastric enzymes), not the liver. Therefore, production of urea is a canonical hepatic function, making option 2 the correct choice.
