Options

A. They belong to single species
B. They are a group of related species
C. They both are morphologically and structurally similar to each other in all respects
D. They can always produce fertile hybrid

Answer

To answer the question about why potato and brinjal belong to the genus Solanum, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Genus and Species**:
- The scientific classification of organisms is hierarchical, with the genus being one of the primary ranks. Each species is identified by a two-part name: the first part is the genus name, and the second part is the species name.

2. **Identifying the Scientific Names**:
- Potato is scientifically named *Solanum tuberosum*.
- Brinjal (or eggplant) is scientifically named *Solanum melongena*.
- Both share the same genus name, Solanum.

3. **Analyzing the Options**:
- **Option A**: "They belong to a single species."
- This is incorrect because potato and brinjal are different species within the same genus.
- **Option B**: "They are a group of related species."
- This is correct as both belong to the genus Solanum, indicating they are related but are different species.
- **Option C**: "They both are morphologically and structurally similar to each other in all respects."
- This is incorrect because while they share some similarities, they are not identical in all respects.
- **Option D**: "They can always produce fertile hybrids."
- This is also incorrect as they do not always produce fertile hybrids.

4. **Conclusion**:
- The correct answer is that potato and brinjal belong to the genus Solanum, which reflects that they are a group of related species.

### Final Answer:
Potato and brinjal belong to the genus Solanum, which reflects that they are a group of related species.
