The correct answer is option 3: Rugae. Rugae are folds or wrinkles in the mucous lining of the empty stomach. These folds allow the stomach to expand and accommodate more food during digestion. When the stomach is empty, the rugae help to increase the surface area of the stomach lining, allowing for better absorption of nutrients when food is consumed. The rugae can stretch and flatten as the stomach fills with food, and then contract and return to their folded state as the food is digested and passes through the stomach. This movement helps with the mechanical breakdown of food and aids in the process of digestion.
