{'small intestine': [1, 0, 1, 1], 'ileum': [2, 0, 3, 1], 'stomach': [0, 0, 1, 1], 'oesophagus': [0, 0, 1, 3], 'caeccum': [0, 0, 1, 0], 'pylorus': [0, 0, 1, 0], 'opening': [0, 0, 1, 0]}

Option 1: Caecum is not the correct answer. The caecum is a pouch-like structure located at the beginning of the large intestine, not the opening of the stomach into the small intestine.

Option 2: Ileum is not the correct answer. The ileum is the final part of the small intestine before it connects to the large intestine. It is not the opening of the stomach into the small intestine.

Option 3: Oesophagus is not the correct answer. The oesophagus, also known as the food pipe, is the tube that connects the mouth to the stomach. It does not connect the stomach to the small intestine.

Option 4: Pylorus is the correct answer. The pylorus is the opening of the stomach into the small intestine. It acts as a valve to regulate the flow of partially digested food (chyme) from the stomach into the small intestine.

In conclusion, the opening of the stomach into the small intestine is called the pylorus, making option 4 the correct answer.
