Options

A. A, B, C & D
B. A, B & D
C. B, C & D
D. A, B & C

Answer

To determine which statements are correct, let's analyze each one step by step:

### Step 1: Analyze Statement A
**Statement A:** Salivary glands are situated just outside the buccal cavity.

- **Explanation:** Salivary glands, such as the parotid, submandibular, and sublingual glands, are indeed located outside the buccal cavity. They secrete saliva into the mouth through ducts. Therefore, this statement is **true**.

### Step 2: Analyze Statement B
**Statement B:** Liver is the largest digestive gland.

- **Explanation:** The liver is known as the largest gland in the body and plays a crucial role in digestion by producing bile, which helps in the emulsification of fats. Additionally, it is involved in detoxification processes. Thus, this statement is also **true**.

### Step 3: Analyze Statement C
**Statement C:** Cystic duct and hepatic duct forms the common bile duct.

- **Explanation:** The cystic duct (which carries bile to and from the gallbladder) and the hepatic duct (which carries bile from the liver) join to form the common bile duct. This duct then delivers bile to the duodenum. Therefore, this statement is **true**.

### Step 4: Analyze Statement D
**Statement D:** Sphincter of Oddi can regulate the release of pancreatic duct and bile duct in duodenum.

- **Explanation:** The Sphincter of Oddi is a muscular valve that controls the flow of bile and pancreatic juice into the duodenum. It opens and closes in response to digestive hormones and the presence of food in the stomach. Hence, this statement is also **true**.

### Conclusion
After analyzing all four statements, we find that:
- Statement A: True
- Statement B: True
- Statement C: True
- Statement D: True

Thus, all statements A, B, C, and D are correct.

### Final Answer:
The correct answer is **ABCD** (all statements are true).
