The correct answer is:
d. gallbladder
Bile is stored in the gallbladder. The gallbladder is a small organ located beneath the liver. It stores bile produced by the liver until it is needed in the small intestine to aid in the digestion of fats. When we eat fatty foods, the gallbladder contracts and releases bile into the small intestine through the bile duct. This bile helps in the emulsification and breakdown of fats, making it easier for the body to absorb them during digestion.
