(a) Exstipulate leaves
(b) Persistent calyx
(c) Racemose inflorescence
(d) Unilocular ovary
(e) Fruits are either berry or capsule.
Of these

Options

A. a, b and e are correct
B. a, c and d are correct
C. a only is correct
D. d and e are correct.

Answer

To determine the characteristic features of the Solanaceae family, we will analyze each option provided in the question step by step.

### Step 1: Analyze the first option - Exstipulate leaves
- **Explanation**: In the Solanaceae family, the leaves are indeed exstipulate, meaning they do not have stipules. They can be alternate, simple, or occasionally pinnately compound with reticulate venation.
- **Conclusion**: This option is correct.

### Step 2: Analyze the second option - Persistent calyx
- **Explanation**: The calyx in the Solanaceae family consists of five sepals that are gamosepalous (fused) and exhibit persistent characteristics, meaning they remain attached to the fruit even after maturation.
- **Conclusion**: This option is correct.

### Step 3: Analyze the third option - Racemose inflorescence
- **Explanation**: The inflorescence in the Solanaceae family is typically cymose, not racemose. This means that the flowers are arranged in a way that the main axis terminates in a flower, which is characteristic of cymose inflorescence.
- **Conclusion**: This option is incorrect.

### Step 4: Analyze the fourth option - Unilocular ovary
- **Explanation**: The ovary in the Solanaceae family is syncarpous and bicarpillary, meaning it has two locules (bilocular) and is superior. Therefore, it is not unilocular.
- **Conclusion**: This option is incorrect.

### Step 5: Analyze the fifth option - Fruits are either berry or capsule
- **Explanation**: The fruits of the Solanaceae family can indeed be classified as either berries or capsules, which is a defining characteristic of this family.
- **Conclusion**: This option is correct.

### Final Conclusion:
Based on the analysis, the correct characteristic features of the Solanaceae family are:
- (a) Exstipulate leaves - Correct
- (b) Persistent calyx - Correct
- (c) Racemose inflorescence - Incorrect
- (d) Unilocular ovary - Incorrect
- (e) Fruits are either berry or capsule - Correct

Thus, the correct options are (a), (b), and (e).
