2. **Solanum tuberosum (Potato)**:
- Solanum tuberosum is the scientific name for potato.
- Potatoes are not fruits; they are modified stems (tubers) that store starch.
- **Conclusion**: Incorrect.

3. **Ficus**:
- Ficus produces a composite fruit known as a syconus.
- The syconus is formed from an inflorescence and contains multiple flowers.
- **Conclusion**: Correct.

4. **Ananas sativus (Pineapple)**:
- Ananas sativus is the scientific name for pineapple.
- Pineapples develop from a cluster of flowers and are classified as a sorus.
- **Conclusion**: Correct.

### Step 3: Count the Correct Answers
From the analysis:
- Lycopersicon: Incorrect
- Solanum tuberosum: Incorrect
- Ficus: Correct
- Ananas sativus: Correct

Thus, **2 plants** from the list have composite fruits that develop from an inflorescence.
