A. Ptyalin
B. Maltase
C. Lactase
D. Sucrase

Answer

To solve the question of selecting the odd one out from the given options, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**: The options given are:
- 1st option: Tylene
- 2nd option: Maltase
- 3rd option: Lactase
- 4th option: Sucrase

2. **Analyze Each Option**:
- **Tylene**: This is an enzyme found in saliva. Its function is to break down starch into simple sugars.
- **Maltase**: This enzyme is found in the small intestine and breaks down maltose into two glucose units.
- **Lactase**: Also located in the small intestine, lactase breaks down lactose into glucose and galactose.
- **Sucrase**: Found in the small intestine, sucrase breaks down sucrose into glucose and fructose.

3. **Compare the Locations**:
- Tylene is found in **saliva**.
- Maltase, Lactase, and Sucrase are all found in the **small intestine**.

4. **Determine the Odd One Out**: Since Tylene is the only enzyme that is found in saliva while the others are found in the small intestine, Tylene is the odd one out.

5. **Conclusion**: The correct answer is **Tylene**.
