C. Sphincter of Oddi
D. Anal sphincter

Answer

To answer the question about the sphincter that separates the esophagus from the stomach, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Sphincters**: Understand the different sphincters in the digestive system. The options provided are:
- A) Pyloric sphincter
- B) Cardiac sphincter
- C) Sphincter of Oddi
- D) Anal sphincter

2. **Locate the Esophagus and Stomach Connection**: Recognize where the esophagus connects to the stomach. The esophagus opens into the stomach at a specific region known as the cardiac region.

3. **Define the Cardiac Sphincter**: The cardiac sphincter (also known as the lower esophageal sphincter) is a circular muscle located at the junction of the esophagus and the stomach. Its primary function is to prevent the backflow of food and gastric juices from the stomach into the esophagus.

4. **Eliminate Incorrect Options**:
- **Pyloric Sphincter**: This sphincter is located between the stomach and the duodenum, not between the esophagus and stomach.
- **Sphincter of Oddi**: This sphincter controls the flow of bile and pancreatic juices into the small intestine, unrelated to the esophagus-stomach connection.
- **Anal Sphincter**: This sphincter is involved in the control of feces evacuation from the anus, again not relevant to the esophagus and stomach.

5. **Conclude the Answer**: Based on the above information, the sphincter that separates the esophagus from the stomach is the **B) Cardiac sphincter**.

### Final Answer:
The sphincter which separates the esophagus from the stomach is called the **Cardiac sphincter**.
