The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Pyloric Sphincter**: The pyloric sphincter is a muscular valve that controls the passage of food from the stomach to the small intestine. 2. **Identifying the Location**: The pyloric sphincter is specifically located at the junction between the stomach and the duodenum, which is the first part of the small intestine. 3. **Function of the Pyloric Sphincter**: Its primary function is to allow the partially digested food (chyme) to enter the duodenum while preventing the backflow of intestinal contents into the stomach. This ensures a one-way movement of food. 4. **Analyzing the Options**: - (a) Stomach and duodenum: This is where the pyloric sphincter is located. - (b) Duodenum and jejunum: This is not correct; there is no sphincter here. - (c) Jejunum and ileum: This is also incorrect; these sections are connected without a sphincter. - (d) Ileum and caecum: This is the ileocecal valve, not the pyloric sphincter. 5. **Conclusion**: Based on the above analysis, the correct answer is (a) stomach and duodenum. **Final Answer**: The pyloric sphincter is present between (a) stomach and duodenum. ---
