D. a,b&c

Answer

To solve the question, we need to evaluate each statement one by one to determine if they are correct or not.

### Step-by-Step Solution:

1. **Evaluate Statement (a)**: "Salivary glands situated just outside the buccal cavity."
- The major salivary glands include the parotid, submandibular, and sublingual glands. The parotid glands are located just outside the buccal cavity, below the ears. Therefore, this statement is **true**.

2. **Evaluate Statement (b)**: "Liver is the largest digestive gland."
- The liver is indeed the largest digestive gland in the human body. It produces bile, which is essential for the digestion of fats. The liver weighs approximately 1.2 to 1.5 kg, making this statement **true**.

3. **Evaluate Statement (c)**: "Hepatic duct not arises from gall bladder."
- The hepatic duct is responsible for carrying bile from the liver. The gallbladder has a separate duct called the cystic duct. Therefore, the statement that the hepatic duct does not arise from the gallbladder is **true**.

4. **Evaluate Statement (d)**: "Sphincter of Oddi can regulate the release of pancreatic and bile duct in duodenum."
- The sphincter of Oddi controls the flow of bile and pancreatic juice into the duodenum. It regulates the release of these secretions at the hepatopancreatic ampulla. Thus, this statement is also **true**.

### Conclusion:
All four statements (a), (b), (c), and (d) are correct. Therefore, the correct answer is that all statements are true.

### Final Answer:
The correct statements are **A, B, C, and D**.
