Answer

To identify the wrongly matched pair from the given options, we will analyze each option step by step.

### Step 1: Analyze Betel Nut
- **Betel Nut**: Also known as Areca Nut, it is obtained from the Areca palm.
- **Classification**: It is classified as a berry, not a true nut.
- **Conclusion**: This is a correct match.

### Step 2: Analyze Bitter Taste of Some Pepper Fruits
- **Bitter Taste in Pepper Fruits**: The statement mentions that the bitter taste is due to triphenyl tetrazolium chloride.
- **Correct Compound**: The correct compound responsible for the bitter taste in some pepper fruits is actually tetracyclic triterpene, not triphenyl tetrazolium chloride.
- **Conclusion**: This is the wrongly matched pair.

### Step 3: Analyze Pome Fruit
- **Pome Fruit**: An example is the pomegranate, which develops from the fleshy thalamus (pseudocarp).
- **Conclusion**: This is a correct match.

### Step 4: Analyze Syconus Fruit
- **Syconus Fruit**: These are composite fruits that develop from a hypanthodium inflorescence, with a cup-like structure.
- **Example**: The fig is a well-known example of a syconus fruit.
- **Conclusion**: This is a correct match.

### Final Conclusion
The wrongly matched pair is the **bitter taste of some pepper fruits**, which incorrectly attributes the taste to triphenyl tetrazolium chloride instead of the correct compound, tetracyclic triterpene.
