What is the main function of the liver?

Correct option is B

Sol. The primary function of the liver includes bile production and excretion, which aids in digestion and the breakdown of fats. Although the liver performs many functions, insulin production is not one of its primary roles. The secretion of gastric juice is primarily a function of the stomach.
Explanation of each option:
· (a) Produces Insulin – The liver does not produce insulin; this is the function of the pancreas. However, the liver does play a role in regulating glucose metabolism and insulin sensitivity.
· (b) Bile production and excretion – Correct answer. The liver produces bile, which is essential for the digestion and absorption of fats in the small intestine.
· (c) Secretion of gastric juice – This is the function of the stomach, not the liver. Gastric juice helps in digesting food in the stomach.
· (d) All of them – This is incorrect because not all the options listed are functions of the liver.
