Read the following statements and choose incorrect statements.

Options

A. Saliva contains a starch digesting enzyme which breaks `alpha-`glycosidic bond.
B. The undigested food becomes semisolid in nature due to the absorption of water in large intestine.
C. Tongue is only used for the finding taste of food.
D. Lymph vessels ultimately release the adsorbed substance into the blood stream.

Answer

To determine the incorrect statement from the provided options, let's analyze each statement step by step.

### Step 1: Analyze the First Statement
**Statement:** Saliva contains a starch-digesting enzyme which breaks alpha-glycosidic bonds.

**Analysis:**
- Saliva does contain the enzyme salivary amylase, which is responsible for breaking down starch into simpler sugars by cleaving the alpha-glycosidic bonds.
- This statement is **correct**.

### Step 2: Analyze the Second Statement
**Statement:** The undigested food becomes semi-solid in nature due to the absorption of water in the large intestine.

**Analysis:**
- The large intestine does absorb water from the undigested food, which results in the formation of semi-solid feces.
- This statement is also **correct**.

### Step 3: Analyze the Third Statement
**Statement:** The tongue is only used for finding the taste of food.

**Analysis:**
- This statement is misleading. While the tongue does have taste buds that help in tasting food, it also plays a crucial role in mixing food with saliva and aiding in swallowing.
- Therefore, this statement is **incorrect**.

### Step 4: Analyze the Fourth Statement
**Statement:** Lymph vessels ultimately release the absorbed substances into the bloodstream.

**Analysis:**
- Lymph vessels do transport absorbed fats and fat-soluble vitamins from the digestive system and eventually release them into the bloodstream.
- This statement is **correct**.

### Conclusion
The incorrect statement among the four provided is the **third statement**, which claims that the tongue is only used for finding the taste of food.
