D. `{:("Name of the plant","Plant part","Drug obtained"),("Thea chinensis","Dried seeds ","Mescaline"):}`

Explanation

To solve the question of identifying the mismatched pair among the given plant names, plant parts, and the drugs obtained from those plant parts, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the First Pair: Erythroxylum coca**
- **Plant Part**: Leaves and young twigs
- **Drug Obtained**: Cocaine
- **Verification**: Cocaine is indeed obtained from the leaves and young twigs of Erythroxylum coca.
- **Conclusion**: This pair is correctly matched.

2. **Identify the Second Pair: Claviceps purpura**
- **Plant Part**: Fruiting bodies
- **Drug Obtained**: LSD (Lysergic acid diethylamide)
- **Verification**: LSD is obtained from the fruiting bodies of Claviceps purpura.
- **Conclusion**: This pair is correctly matched.

3. **Identify the Third Pair: Cannabis sativa**
- **Plant Part**: Leaves, resin, and inflorescence
- **Drug Obtained**: Bhang and Hashish
- **Verification**: Bhang and Hashish are indeed derived from the leaves, resin, and inflorescence of Cannabis sativa.
- **Conclusion**: This pair is correctly matched.

4. **Identify the Fourth Pair: Thea chinensis**
- **Plant Part**: Dried seeds
- **Drug Obtained**: Mescaline
- **Verification**: Thea chinensis, commonly known as the tea plant, primarily yields caffeine from its dried leaves, not mescaline, which is a hallucinogenic compound obtained from cacti.
- **Conclusion**: This pair is mismatched.

### Final Conclusion:
The mismatched pair is **Thea chinensis - Dried seeds - Mescaline**. The correct drug obtained from Thea chinensis is caffeine, not mescaline.
