Answer

To determine the correct combination of a family and its respective members, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Families and Members**: Look at each option and identify the family and the members listed under that family.

2. **Analyze Option 1**:
- Family: **Fabiaceae**
- Members: **Colchicum** and **Trifolium**
- Analysis: Colchicum is actually a member of the family Liliaceae, not Fabiaceae. Trifolium is indeed a member of Fabiaceae. Since one member is incorrect, this option is not valid.

3. **Analyze Option 2**:
- Family: **Solanaceae**
- Members: **Vidinia somniferum** and **Petunia**
- Analysis: Both Vidinia somniferum and Petunia are indeed members of the Solanaceae family (the potato family). This option appears to be correct.

4. **Analyze Option 3**:
- Family: **Liliaceae**
- Members: **Sysbenia** and **Asparagus**
- Analysis: Sysbenia is a member of the family Fabiaceae, while Asparagus belongs to Liliaceae. Since one member is incorrect, this option is not valid.

5. **Analyze Option 4**:
- Family: **Asteraceae**
- Members: **Nicotiana tabacum**
- Analysis: Nicotiana tabacum (tobacco) belongs to the Solanaceae family, not Asteraceae. Therefore, this option is also incorrect.

6. **Conclusion**: After analyzing all options, the only correct combination of family and its respective members is found in Option 2: Solanaceae with members Vidinia somniferum and Petunia.

### Final Answer:
**Option 2: Solanaceae - Vidinia somniferum and Petunia**
